Pen Review: Skogsy Pens Low Volume Eyedropper

May 29, 2024

Now that we're about four weeks removed from the 2024 Chicago Pen Show, I'm in a position to share my thoughts on the first of several pens I acquired at that show, including the one featured here: the Skogsy Pens Low Volume Eyedropper! Skogsy Pens is run by Zach and Amy Skogsberg, a husband-and-wife team where Zach is the primary maker and Amy can always be found handling the business end behind the table at pen shows! It’s been delightful to get to know them over the past couple of years, and what's amazing to me is that Zach has only been making pens since 2021, yet I've found his pens to be of consistently high quality with unique designs and material combinations. My favorites include Micarta and, as shown here, polished ebonite.

The combination of polished acrylic and ebonite is gorgeous and immediately when I saw this pen at the Skogsy Pens table I knew that I would not leave the show without it.

So What is The “Low Volume Eyedropper” System

The Low Volume Eyedropper showcases Zach’s creativity and innovation, combining beige and black ebonite for the cap and section with a polished clear acrylic barrel, drilled out to function as an eyedropper. It’s a cool look. For the uninitiated, eyedropper pens can feel intimidating. They typically involve filling the barrel of the fountain pen directly with ink using a pipette or dropper, and sealing the barrel threads with silicone grease or an o-ring. Most eyedroppers hold a LOT of ink, which newer users often perceive as risky because it can cause a big mess if the pen leaks from the barrel or section or "burps" ink out the front of the nib due to changes in air pressure or temperature. The Skogsy "Low Volume" eyedropper is an experimental design that looks to mitigate some of the everyday complications inherent in eyedropper pens, and make them more user friendly.

While this pen is on the shorter side for me, it’s proportionate enough in terms of diameter to maintain comfort.

The Low Volume Eyedropper - as the name implies - has been intentionally designed to hold a smaller volume of ink than your typical eyedropper in order to limit the amount of ink flowing to the feed and to allow for additional insulation of the ink chamber. (i.e., The smaller the ink chamber, the thicker the barrel, which means more material between the ink and your hand, which in turn limits temperature fluctuations that cause burping.) I understand that some additional modifications have also been made to the ebonite feed and the section to moderate the ink flow - something that can be particularly important with an eyedropper as most eyedroppers are wet writers to begin with and an ebonite feed will exacerbate that issue. I'm pleased to report that that system functions as intended: Even as I've emptied the pen, I've experienced no burping or excess flow as the eyedropper writes toward empty, and the ebonite feed maintains a steady stream of ink that's pretty much perfect for my preferences with a broad nib.

The cap/barrel seam sits dead center. The cap is 2.75” long and the exposed portion of the barrel is the same length.

The Pen's Design: Relatively Short and Sweet with a no. 8 magna carta nib

Zach originally got into making fountain pens because he had a hard time finding a size and shape that appealed to him. As he points out in his introduction, compact pens with wider grip and barrel can be difficult to find, especially at an accessible price point. It can be even harder to find a pen with these proportions that features a larger nib - personally I feel that a No. 8 nib simply looks better on a pen of this size than a No. 6. Fortunately, lower-cost stainless steel No. 8 nibs have become more widely available as both JoWo and Magna Carta now supply them to penmakers, with Magna Carta currently the most popular. (Both the Skogsy Low Volume Eyedropper and the Edison Jameson that I picked up in Chicago feature these Magna Carta nibs.)

My pen came with two nib options. The Magna Carta has been installed since the Chicago Pen Show, but I also love that surfboard design on the JoWo No. 6! (Skogsy Pens is located in San Diego.)

I will note that the Magna Carta nibs can need some tuning, which may include not only smoothing but heat-setting the nib to the feed. This process is not terribly complicated for an experienced user to do by themselves, but if you're not comfortable performing minor work on your own nibs I would highly recommend purchasing your pen at a pen show where Zach can adjust your nib in person to fit your preferences.

The Magna Carta stainless steel nib features no branding. It’s a nice standard broad nib, but….

The ebonite feed is what makes the writing experience! Adding extra flow really does up the game here.

The finish on my pen is flawless. The clear acrylic barrel is polished to perfection without any noticeable tool marks, the threads are smooth, and the ebonite on the cap and section shines. And check out that swirl at the top of the cap....

Perfectly centered.

The Low Volume Eyedropper measures approximately 5.5 inches capped, 5 inches uncapped, and 6.5 inches posted. It's a very comfortable length for me to use either posted or unposted, though I think I prefer unposted as the pen feels more balanced. The gently concave, wider-diameter section offers a good grip area, and ebonite is one of my favorite materials to write with because it takes on a warm feeling in the hand. This pen practically begs to be used everyday, and offers an extremely pleasant writing experience over longer sessions at work or at home in my journal(s).

The cap posts deeply and securely, though I think I prefer to use this one unposted.

What About the Ink and Paper Used in This Review?

In addition to test-driving the Low Volume Eyedropper, I used this review as an opportunity to try out a new ink and rediscover a favorite paper. I've always found brown/beige pens - and definitely clear-barreled eyedroppers - as excellent vehicles for showcasing red inks, so for this review I inked the pen up with Tom's Studio "Mulberry". Mulberry is a gorgeous deep burgundy that is what I consider a "solid color": without shading or sheen but it has a beautiful dark red hue with purple undertones.

What is it about brown/beige/grey pens and red inks?

As I mentioned above, the broad No. 8 Magna Carta Nib writes a bold wet line, and I had no issues with the Mulberry feathering or bleeding on the paper I've used here, which is the Blackwing "Illegal Pad". I've written before on my frustration with finding decent, reasonably priced legal-style pads capable of handling fountain pen ink, and I'm glad that Blackwing has now made these pads more widely available. Cool Note: The lined pads shown here feature a legal/steno layout, which is a lined pad with a center dividing line that we attorneys have traditionally used for various purposes such as organizing questions and corresponding answers at deposition or in court, as well as for checklists and research task management.

Takeaways and Where to Buy

At the Chicago Pen Show, the Skogsy Low Volume Eyedropper was priced at $340, which included a stainless steel Magna Carta No. 8 nib AND an extra Jowo No. 6 section and nib with the Skogsy surfboard design. I consider this excellent value given the craftsmanship and versatility. I have not yet tried out this pen with a No. 6 nib, and I’ll be interested to see whether it changes my perception of the balance or the writing experience.

The polished ebonite showcases a good bit of grain. Polished ebonite is one of my favorite fountain pen materials, and highly underrated.

As of the date of this post, Skogsy Pens does not have any Low Volume eyedroppers listed for sale on their website, as they are in the middle of Pen Show Season and stock needs to be reserved for shows (This is frequently the case with many smaller makers.) If you're interested in this particular pen, you have a few different options: Keep checking their online shop or contact them directly to place an order for a commission, follow Skogsy Pens on Instagram, or even better, visit them at a pen show! They list all upcoming shows online, and will be appearing at the Dutch Pen Show in June, the D.C. Pen Show at the beginning of August, and the San Francisco Pen Show at the end of August.

Another writing sample with the Mulberry ink, this time on Midori MD Cotton Paper.

The ink and paper featured in this review can be purchased in our own shop, as we carry the entire line of Tom's Studio Fountain Pen Inks, including Mulberry. You can read more about these inks ($16 for a 50ml bottle) and view swatches here. We also sell the Blackwing "Illegal Pads", which come in packs of two pads (priced at $20) and are available in blank, dot, and classic "legal pad lined" formats.

To Eyedropper or Not to Eyedropper, That Is the Question

July 3, 2022

As part of this general trend of downsizing everything to a more manageable size, I’ve been trying to write dry all of the various fountain pens that I have inked up, and wow, is that hard to do when so many of them are cartridge-converter pens set up as eyedroppers. I go back and forth on whether, overall, I enjoy eyedroppering. While it’s nice to have the ginormous ink capacity, I’m not sure that convenience outweighs the various downsides given where I live and my current work/life situation.

A Bit of Background

For those new to pens, an “eyedropper” or “eyedroppering” is when you manually fill the barrel of a fountain pen with, well, an eyedropper directly from a bottle of ink. In today’s fountain pen market, there are two types of eyedroppers: Japanese-style eyedropper pens, which comes equipped with a valve system you can use to prevent leaks when you’re not writing, and the “converted” eyedropper, which is essentially a cartridge-converter pen sealed in a manner that allows you to use the full barrel as an ink reservoir. Eyedropper fountain pens can be great for those of us who do a lot of writing, as they can easily hold 3-5ml of ink in the barrel, depending on the size of the pen.

The Schon DSGN Ultem Fountain Pen in Amber (right) is eyedroppered.

To Eyedropper, or Not to Eyedropper

At this point in my fountain pen “career,” I’m not as much of a serial ink changer and mostly enjoy using the same handful of colors, so I can appreciate not having to refill fountain pens very often. That said, the recent hot weather here in balmy Tennessee reminds me of the many downsides to eyedropper fountain pens, namely drastic temperature swings moving outdoors to the car to the office, which causes the pen to burp - no, belch, ink into the cap unless there’s a valve mechanism like that available in the Opus 88 series. For this reason, I’m personally moving away from eyedroppers in favor of other filling options, unless the pen in question has a shut-off valve.

The sections of the Schon DSGN Engineered Plastics Fountain Pens come with o-rings installed. No silicone grease is necessary, though some people choose to use it for double protection against leaks.

For those who live in more moderate climates, or who view maximizing ink capacity and eyedroppering as a challenge they absolutely cannot pass up, there are a few things you can do to ensure that your eyedropper fountain pens behave and don’t cover you in ink.

  • Add O-Rings or Silicon Grease. If you don’t seal the threads around the section and the screw in nib unit, ink will eventually migrate up the threads and leak. Silicon grease is inexpensive and can be purchased from many pen shops. You only need to use a small amount (just enough to coat and fill the area between the threads), and for the section, a thin rubber o-ring will work as well. (Schon DSGN plastic pens, discussed below, already come equipped with o-rings and “eyedropper ready”.)

  • Fill ‘er Up! If you’re going to be flying with the pen, or otherwise moving between locations with large temperature or air pressure swings, make sure the pen is full before travel. It’s counterintuitive, but a full pen without any air in the barrel is much less likely to leak. The number one cause of fountain pen “inkcidents” is air expansion due to shifts in temperature and pressure, which causes air in the barrel to expand, pushing ink out the nib. For more on traveling/flying with fountain pens, check out this post here.

  • Keep the Pens Nibs Up. The main reason I prefer the Opus 88-style eyedropper pens is because you don’t have to worry about this factor. I’m back to commuting 3-4 days a week, so my pens are going with me in the car each day. In addition to the wild temperature swings we’ve been experiencing, I’ve had issues with ink leaking out if my briefcase falls over or my pen case shifts sideways, not to mention if I’m flying and have to slide my carry-on bag under the seat or into the overhead compartment.

Franklin-Christoph Model 20 (left) and Model 03 (right, orange pen) generally make good eyedroppers if you remove the converter and apply grease.

What Are the Best Fountain Pens for Eyedroppering?

Generally speaking, any plastic or acrylic pens without holes in the barrel or internal metal parts can be eyedroppered. (Metal doesn’t play well with liquid, though some people have had success with non-reactive titanium. Personally, I don’t tempt fate.) That said, there are a few brands that market their pens as “eyedropper friendly,” with caveats. Note that these will all require some work on your part to convert from cartridge-converter to eyedropper, as I’ve noted above, with the exception of the Opus 88 eyedroppers.

  • Most Franklin-Christoph Fountain Pens. I’m partial to the Model 20, which has a slip cap and a No. 6 JoWo Nib. Their smaller pens that feature the No. 5 JoWo nib also have better inkflow when eyedroppered, in my opinion. (This is due to the nib and feed, not the pen design.)

  • Schon DSGN Engineered Plastics Collection. You can read my full write-up here, but as I mentioned above, these pens come equipped with multiple o-rings to make them as eyedropper-friendly as possible.

  • Most Acrylic or Ebonite Bespoke or Custom Pens. Buy a pen from Shawn Newton or Edison Pens, and you can probably eyedropper it, provided you add silicone grease or an o-ring. If you’re ordering a custom pen specifically to be used as an eyedropper, let them know and they may be able to design the pen to maximize the ink capacity.

Pen Review: Opus 88 Omar Demonstrator

October 17, 2020

Those of us with occupations that involve significant amounts of writing are constantly on the lookout for comfortable pens with a reliable nib and a large ink capacity. Time and again, whenever I’m asked for such a recommendation, I keep returning to Taiwanese brand Opus 88. If you aren’t looking for flash or luxury, and you simply want a large, lightweight fountain pen that you’ll have to refill infrequently, the brand should be at the top of your list.

Each Opus 88 Fountain pen comes with a glass eyedropper in the box. Montblanc Hitchcock not included.

While Opus 88 has been at the vanguard of the recent trend towards ever-larger pens, they take a different approach in that their larger writing instruments are actually designed to maximize comfort and ink capacity, not to showcase rare materials or to drive up the price point. The “Omar” fountain pen, the model I’m looking at today, might be one of the largest fountain pens I’ve used recently, but it’s also one of the most comfortable, and it holds roughly 3.5ml of ink!

3.5ml of liquid gold.

Ok, but there are tons of humongous acrylic pens on the market these days that you can turn into an eyedropper relatively easily. What makes Opus 88 unique? Opus 88 uses what’s known as a “Japanese Eyedropper” filling system, which incorporates a “piston” that, when closed, activates a system of stoppers and gaskets (o-rings) to minimize the chance of leakage. One drawback to “hacked” eyedropper fountain pens is that they tend to burp ink into the cap when the pen gets jostled in a bag, or when the pen is exposed to fluctuations in temperature and air pressure, such as in the car or on an airplane. Before Opus 88 brought this filling system into the mainstream, Japanese-style eyedroppers were typically found on much more expensive urushi pens from brands such as Danitrio.

If you plan on writing for longer sessions with a Japanese-style eyedropper, open the valve to allow a continuous flow of ink to the nib, similar to how you would write with a Pilot Custom 823 or TWSBI Vac 700.

As I mentioned above, the Opus 88 Omar is large, but also quite comfortable. While you may see stock photographs of this pen posted, it’s way too big for me to use in this manner. Since the Omar will likely serve as a desk pen, as opposed to an “on the go” writing instrument, I’m perfectly happy using this pen unposted. The JoWo No. 6 medium nib writes a predictably smooth line, and the eyedropper filling system ensures a steady flow of ink to the nib. The Omar makes a great workhorse.

The Opus 88 Omar does technically post, but not deeply and the pen is so large that it ends up looking a almost clownish.

Takeaways and Where to Buy

Though I was initially skeptical about the size of the Omar, it turned out to be one of my favorite pens in the Opus 88 lineup. If you’re not a serial ink-changer, and don’t mind the relative complexity of filling a pen using an eyedropper, the Omar might just be the perfect choice for your upcoming NaNoWriMo marathon. You can purchase the Opus 88 Omar in a variety of colors and materials from site sponsor Goldspot. The pen pictured here is the clear demonstrator, currently priced at $123.

Pen Review: The Moonman M2 Eyedropper Fountain Pen

March 28, 2018

Lately I've become a bit enamored with all the unique (and inexpensive!) pens coming out of China. Even just a couple of years ago, when someone in the pen community mentioned "eBay Pens" or "Chinese Pens," they were referring to extremely cheap pens by Jinhao, Baoer, and others that could be found priced at $5 or less. These pens are, of course, still available, and there's a reason they're so cheap: manufacturers perform little to no quality control, and it can be a total crapshoot whether or not you receive a pen that actually writes out of the box. I most recently experienced this issue with a Monteverde Monza, which I've since learned is a rebranded Jinhao.  

The acrylic on the Moonman M2 is well-polished, both inside and out.

The overall landscape, however, has changed over the past year or so. Whether it's a question of manufacturers actually upping their game, or simply different (and higher-end) Chinese pens being made available internationally for the first time, I've recently purchased several sub-$20 fountain pens that significantly outperform their price point and are legitimately good pens. The overall winner so far is the Moonman M2, a clear acrylic eyedropper fountain pen with one of the best out-of-the-box steel nibs I've used. 

I use the Moonman M2 as a desk pen, shown here sitting atop my Logitech K780 Keyboard. I typically use the keyboard's tablet/phone holder as a pen rest.

I don't know much about Moonman, but from what I've read elsewhere, it's a brand run by stationery and pen enthusiasts who source their pens from a factory and then further tunes/customizes them. Their enthusiasm shows - Moonman plainly has put a lot of attention into the M2. While the pen itself is a straightforward design, the acrylic is well-polished, and the pen sports an attractive red anodized cap band that looks especially good if you have the pen filled with red ink. (Montblanc Alfred Hitchcock is my current choice.)

Note that this pen is eyedropper-only. If you prefer to use a cartridge/converter filling system, this won't be the right pen for you. Kudos to Moonman for including a very nice glass eyedropper in the box alongside the pen. I like this eyedropper better than the one that accompanies the Opus 88 Koloro pens, since this one has a "needle tip" that makes it easier to get the ink down into the barrel with minimal mess.

As I mentioned earlier, the nib on this pen is a stunner. I wouldn't call it a needlepoint, but it's definitely a true extra-fine that's been perfectly tuned for smoothness and flow. Don't be thrown off by the lack of a custom imprint and the "Iridium Point" engraving - someone who knows what they're doing has worked on this nib. I also don't think my pen's an outlier - the reviews I've read have been uniformly outstanding.

The Moonman M2 is a great length. posted or unposted. The section is comfortable, with unobtrusive threads that take about 2 turns to open and close.

Takeaways and Where to Buy

The extra-fine nib on my Moonman M2 might be the best nib on a "cheap" pen that I've ever experienced (and certainly the best Chinese-made nib I've ever used), making this a no-brainer purchase for me to recommend, especially if you like eyedroppers. Which brings me to the question of where to buy them. Since Moonman pens aren't stocked at retailers outside of China, as far as I know, and are made in relatively small batches, you may have to consider a variety of avenues to get your hands on one. You can find them easily on eBay at a range of listed price points, though you should pay close attention to the shipping charges which usually causes the total price to average out into the $10-15 range.

Another shot of the nib and section.

Further Reading

I discovered the Moonman M2 via Frank Underwater, a great blog to read in general, and especially if you're interested in further exploring the world of Chinese pens. Also, PenTalk has an excellent video with a lengthy review, including footage of the Moonman M2 in action. 

I've ordered a handful of pens over the past couple of months, some of which are still on their way. I've previously offered my thoughts on the Wing Sung 618 and 698 piston fillers, which also represent great value but the nibs aren't as good as the Moonman M2. Stay tuned for a more detailed follow-up review on these!

Pen Review: Opus 88 Koloro Demonstrators

January 27, 2018

Since entirely new fountain pen brands are few and far between, those that do hit the market tend to immediately catch my attention, especially when the pens being offered are in any way unique. Enter Opus 88.

Opus 88 is a Taiwanese company that, from what I have gleaned on pen forums and other “unofficial” (and unverified) sources of research, previously has manufactured pens on a contract basis for other, better-known pen companies. This past fall, they started selling their own "Opus 88" branded pens in the United States through Pen Chalet. The pens apparently have sold very well so far, with certain colors and nib sizes periodically going out of stock.

Design and Build

Opus 88 currently offers two models: a smaller "Koloro" demonstrator that is available in four colors: blue/tan, blue, yellow/tan, and red, and a larger transparent demonstrator with black trim. The Koloro pens feature a unique combination of ebonite and acrylic. The majority of the barrel is constructed from acrylic, while most of the cap and the blind cap are ebonite. The only trim is a somewhat plain chrome clip.

Both Opus 88 models feature minimal branding, just "Opus 88" on the cap. On the Koloro pens, the branding is engraved. On the larger demonstrator, shown below, it's screen printed, which doesn't look as nice and likely won't be as durable. 

The transparent demonstrator (also labeled the “Koloro” on Pen Chalet’s website, but I think that may be a typo) is much larger, made entirely from transparent polished acrylic, and features matte black-plated trim. Both pens are well-made for their price point, with smooth threading on the caps, sections, and blind caps, and no readily apparent tool marks or other manufacturing artifacts. For unique pens hovering around the $100 mark, the Opus 88 pens represent good value.

Filling System

All of the Opus 88 pens released to date are Japanese-style eyedroppers. It’s a pretty basic system: To fill the pen, you unscrew the section and use the included glass eyedropper or a syringe to fill the barrel with ink. I haven’t officially measured the ink capacity, but these pens hold a lot. Pen Chalet states that the smaller pens hold 2ml, but my guess would be that this estimate is on the low end. The larger pen holds nearly 4ml, as I was able to get almost an entire sample vial into the barrel. The section on each pen comes pre-fitted with an o-ring to prevent leakage, and I opted to add a bit of silicon grease to the section threads just to be on the safe side, since I travel so much and an accident could be disastrous.

In order to increase ink flow to the nib, all you need to do is open the valve, which unscrews like a piston knob at the rear of the barrel. 

A note on the “Japanese-style” eyedropper system: While the Opus 88 pens are fitted with blind caps that unscrew, this is not a piston-filling or converter pen, and the blind cap does not force ink into or "prime" the feed. Eyedroppers are entirely gravity driven. The purpose of the blind cap is to control a stopper, which seals off ink flow from the barrel to the nib so that ink doesn’t leak out when you’re not writing - a common occurrence in eyedroppers without this shutoff valve mechanism. Without a way to restrict ink flow, shaking, drops, and especially temperature and altitude fluctuations can cause the ink in an eyedropper to expand and “burp” into the cap, into your bag, or even onto the paper when you’re writing. If you plan on using this pen extensively at work or while travelling, as I have, the shutoff valve is a good feature to have, and previously I had only seen it on extremely high-end Japanese Urushi eyedroppers such as those made by Danitrio.

A shot of the Opus 88 Koloro demonstrator with the blind cap unscrewed and the valve opened. When the blind cap is screwed all the way down, the plunger/stopper seals off the nib and feed, keeping the ink in the barrel. 

The flip side is that in order to write for extended periods of time, you will need to open the shutoff valve by slightly unscrewing the blind cap to allow a continuous flow of ink to the feed, much as you would need to do with a TWSBI Vac or Pilot Custom 823. This allows ink to flow from the barrel into the section and saturate the feed. You can close the valve at this point, and with finer nibs should have enough ink to write for a page or two. I tend to leave the valve open all day while I’m at work, and close it up when I get ready to go home. The system works incredibly well. With the valve open, I’ve never had these pens dry out, skip, or hard-start.

Writing Experience

Opus 88 uses reliable stainless steel German nibs made by JoWo. The Koloro demonstrators use JoWo No. 5 nibs, while the larger transparent demonstrator uses a No. 6 nib. All three of my pens arrived well-tuned and did not require any nib adjustments. JoWo nibs are among the best stock stainless steel nibs, though I do find that the smaller No. 5 nibs work best in eyedropper or cartridge pens because they tend to write very dry when attached to a converter. I suspect this has something to do with the construction of the feeds in the No. 5 nib units, but I haven’t done enough experimenting to say for sure.

Nib size comparison: JoWo No. 5 (left) vs. No. 6 (right)

Both Opus 88 models are quite light, and therefore very comfortable to write with for long periods of time. The Koloro posts easily, even with the blind cap partially unscrewed, and I tend to use the smaller pen posted. The big transparent eyedropper doesn’t post, so it mainly sits at my desk at home.

Takeaways and Where to Buy

As far as I’m aware, Pen Chalet is the exclusive distributor of Opus 88 fountain pens in the United States, though that may change as these pens attract more attention and become more widely available. Personally, I hope they do, because Opus 88  should have a hit on their hands with eyedropper fans who need a pen that holds a ton of ink and who don’t want to worry about the perils of temperature fluctuation and messy ink burps. Eyedroppers aren’t for everybody, however.  They tend to be messier to fill and to clean, and if you like the look of these pens I’d recommend that you start out with one of the smaller, less expensive Koloro demonstrators, which is a much more practical size that will appeal to most people.

The multicolor ebonite and acrylic “Koloro” demonstrators are currently priced at $93 (minus whatever discount code Ron has running at any given time). The transparent demonstrator is available for $120 (minus applicable discounts).
