First Impressions: Hands-on with the Uni Zento Signature!

Ok, so I finally got my hands on a Uni Zento Signature - Uni’s latest “it” gel pen that flies off shelves so fast in Japan that it hardly ever makes it’s way into the U.S. market, and when it does, it often appears at grossly inflated secondary market prices. (I’ve seen these pens priced as high as $200+, but fortunately as they become more available this degree of silliness is less common.) I’ve been trying to get my hands on a Zento Signature for about a year, and when Vanness Pens obtained a (very) small shipment for the California Pen Show in February, I managed to snag one of the black ones in the .5mm tip size. After a few weeks of use, here are my initial impressions.

What I Like About the Uni Zento Signature

• Magnetic Cap. The Zento Signature features a magnetic cap which closes and posts securely. This feature alone makes the Signature an excellent pen for everyday carry. Standard “click” gel pens can accidentally deploy in your bag or pocket, causing a mess. You don’t have that issue with the Signature.

• Sturdy Clip. The Signature features an upgraded metal clip that’s a bit heavier duty than the wire clip on the standard and Flow pens. I haven’t had the pen long enough to know whether it will make a real long-term difference in terms of durability, but it feels secure and does lend the pen a higher-end look.

• Matte Grip. The grip section on the Zento Signature has a matte texture that reduces slippage in the hand. The metal barrel on the Zento Flow might be a touch slick for some people. If you’re writing outdoors, in a variable travel environment, or if you tend to have sweaty hands, the Signature is a good choice.

• All-Metal Construction. The Zento Signature feels durable due to the nearly all-metal construction, including interior metal threads. There’s even an o-ring to prevent leakage if a refill goes bust.

Do I Prefer the Zento Signature Over the Zento Flow? A Few Considerations that have me leaning towards the Zento flow

• Price Point. Even at the standard pricing ($30), the Zento Signature is nearly 3x more expensive than the Zento Flow, and 10x more expensive than the standard Zento. All three pens use the same refill, so in order to justify the price difference, you need to really like the format. I would NOT suggest that anyone pay $100-200 on the secondary market for a Zento Signature under any circumstances - it was never intended to be sold at this price point and the value proposition is not there.

• Balance. I don’t consider the Zento Signature unbalanced, but for longer writing sessions the Zento Flow fits my hand better. Posted, the Signature is only slightly shorter, but the difference in weight and balance feels more pronounced. I think I prefer the more front-weighted Flow overall.

• Hype. The stationery industry goes crazy over certain products from time to time, and I’m usually able to ignore the hype but with the Zento Signature it can be impossible. This pen has drawn so much attention that I dislike using it in public and carrying it with me at shows and meetups due to the number of people constantly asking whether I’m willing to sell it. (I’m not.) In my opinion, this pen is nice but does not justify the level of social media FOMO-driven hype that it receives.

Most of the price point of the Zento Signature goes into the metal barrel. As you can see, the barrel threads are metal as opposed to plastic, which suggests that the pen will be more durable over time as one would expect for the price point. That said, both pens use the same refill, so your writing experience is nearly identical.

Further Reading on the Uni Zento Lineup

I’ve previously reviewed the standard Uni Zento and the “mid-tier” Zento Flow, which uses the same refill and features an upgraded metal barrel in five different finishes. I think the Zento refill is excellent, and consider these pens exceptionally good everyday writers for those who value a smooth writing experience. The Zento is designed to be “low friction”, and performs as advertised. At the end of the day, is the coveted Zento Signature 2-3x as good as the Flow? If you’re just looking to write with a Zento, probably not, but if you are looking for a pocket-carry EDC pen with a magnetic cap, at $30 the Zento Signature is a reasonable choice as long as you can find one at standard pricing.

We currently have a fairly large selection of Standard Zentos and Zento Flow pens in stock in our shop, including the cool “Birch” Flow that pairs a white upper barrel with etched aluminum. We recently added some .7mm options for those who prefer a wider tip size. Unfortunately, we do not have any Zento Signatures available for sale as they remain largely unavailable in the U.S. Our friends at Vanness Pens are also currently sold out. Please note that I am not interested in selling my personal pen and generally do not respond to emails and comments regarding purchases from my personal collection. Thank you for understanding!

Pen Review: The 2025 Pilot Prera Revamp

Believe it or not, there is a very popular pen that I’ve never reviewed, and that pen is the Pilot Prera. The Prera has been around for years, and often recommended as a solid “next step” option for those upgrading from a pen like the Pilot Kakuno, Metropolitan, Explorer or other basic “entry level” pen. The $50-75 price range can be pretty sparse, and the Prera has long been one of the stalwarts in this bracket.

View fullsize

Why have I never reviewed the Prera? Well, for years the Prera was only available to the U.S. market in a clear body style that never appealed to me enough to buy. Since I run a highly curated retail store, I never previously explored carrying the Prera since I tend to focus mostly on pens that strongly appeal to me personally and that I like to recommend. Was this 100% fair to the Prera? Probably not, but in any event, the recent release of four new solid colors (Porcelain White, Honey Yellow, Empress Teal, and Cinnamon Brown) caught my attention and prompted me to reconsider. I’ve been using a yellow Prera nearly exclusively for the past two weeks and I like it.

View fullsize

The Pilot Prera compared to a Kaweco Sport, Pilot Custom 74, and Tom’s Studio Wren. The Kaweco Sport and the Tom’s Studio Wren are what I would consider true pocket pens, while the Custom 74 is more full-size so you can see how they compare.

So what are my thoughts? For starters, I can see why this pen is popular. Compact fountain pens such as the Kaweco Sport, Sailor Pro Gear Slim, and Pilot E95s are favorites for a reason, in that they “carry small and write big”. While I wouldn’t put the Prera in the “pocket pen” category (it has a friction-fit cap), it’s small enough to be portable, and it would fit nicely with a planner or small organizer. Posted, the Prera is large enough for me to use comfortably for longer writing sessions, and I’ve used it to journal nightly without issue.

Though labeled a medium, the steel Prera nib could best be characterized as a “Fine Medium” nib, IMHO. It’s a perfect width for my own everyday writing.

Pilot’s main draw, in my experience, is the brand’s rock-solid reliability. The stainless steel medium nib on my Prera is a smooth writer and on the fine side for a medium steel nib, which I prefer. While not inexpensive at $64, the Prera does ship with both a cartridge and converter, so you’re able to use both Pilot cartridges and bottled ink out of the box.

Takeaways and Where to Buy

Though more expensive than the Metropolitan or Explorer, the Prera offers a more traditional flat-top format somewhat reminiscent of the Sailor Pro Gear or Pro Gear Slim. A reliable writer that will perform as expected, these pens are great for those seeking a fountain pen with a “professional” look, or simply a more compact writing instrument for use on the go. Personally, I think the new colors are outstanding, with Honey Yellow and Empress Teal being my favorites since they remind me of classic vintage pens. Cinnamon Brown is also more of a burgundy than a true brown, and not a color that you typically see from Pilot.

View fullsize

The Prera is priced at $64 and ships with a squeeze converter included. Currently available with either a fine or medium stainless steel nib, I understand that additional nib options are on the way, including a steel stub/italic that I look forward to trying out once it’s available. For now you can find the new Preras in our own shop, and we may consider adding the clear Prera’s going forward if there is enough interest.

Multi Pen Versatility: Combining the Pilot 4+1 Multi Pen with the Uni Style Fit Gel Refill

When I had ordered these Pilot 4+1 Multi Pens, I knew that they used the exceptionally good Acro ink BVRF-9 low-viscosity refill. I was NOT aware that Uni’s Style Fit gel refill uses the same format, and therefore fits this pen. For today, I wanted to do a quick post showing off this feature because I love when multi pens are versatile enough to allow you to use both ballpoint and gel inks at the same time, and the contoured grip on this Pilot makes it not only versatile but extremely comfortable to use.

View fullsize

Here, you can see that I have taken one of the blue Pilot 4+1 pens and swapped in two .5mm Style Fit refills in Mandarin Orange and Blue-Black. The Acro Ink and Style Fit refills are exactly the same size and shape, allowing you to choose from among the 16 Style Fit gel colors in addition to the Acro Ink set.

The Acro-Ink Refill (left) alongside the Style Fit (right). Note that the Style Fit and Pilot BVRF-8 refills DO NOT fit Uni 4+1 Multi Pens, as these use a shorter Jetstream Refill. It’s also excellent but just a different format.

Both the Uni Style Fit and Acro Ink refills provide a smooth writing experience. Of course, the edge in smoothness and color saturation will go to the gel pen, but Pilot’s Acro Ink deserves a place among the best ballpoint refills on the market. We added one of these Pilot multi-pens to our most recent Patreon Curated Box, and received a ton of positive feedback on the stock refills so these will be a shop staple for as long as we can continue to get them. (They are imports.)

Takeaways and Where to Buy

Personally, I favor the Pilot 4+1 body over the Uni Style Fit Meister 5, though both are good. The contoured wood grip on this Pilot Multi Pen is among the most comfortable I’ve used, and I was thrilled to discover that there is a gel refill I can pair with it that offers .28mm, .38mm, and .5mm options in 16 different colors. (Just to be clear, the reverse is also true - the Style Fit body will take the Pilot refill.)

You can get the Pilot 4+1 and Uni Style Fit Multi Pens in our shop, along with the refills for both. As noted above, the Pilot 4+1 ships with four .5mm Pilot BVRF-8 refills (black, blue, red, and green, plus a .5mm mechanical pencil). The Uni Style Fit bodies are sold separately from the refills, so you can assemble your own customized pen.

Pen Review: Is the Uni Zento Gel Pen Worth the Hype?

One of the most-discussed releases of the past year has been the Uni Zento gel pen, which has captured the attention of the stationery communities in both Japan and the U.S. In particular, the “Zento Signature” - which features a cap as opposed to your typical retractable mechanism - prompted rushes reminiscent of the Uni Kuru Toga Dive mechanical pencil. While I’ve yet to get my hands on one of these “upscale” models for an extended test drive, I’ve had the opportunity to write with both the standard Zento and the slightly upgraded “Zento Flow” (both retractables) for a couple of weeks now. While I’m not sure I would pay more than standard retail for any version of this pen, the Zento is an excellent gel pen and so far I prefer it over the Uni One and any of the basic Uni Signo “office” inks.

So What’s the Story Behind the Zento?

Uni’s gel pen lineup can be confusing - the company has released multiple iterations of your standard black/blue/red gel pen and left them all on the market simultaneously, the only difference supposedly being different inks that to most people will seem quite similar. The Zento is advertised as formulated for “stress free” writing, which apparently refers to a combination of smoothness and cushion. The Zento is indeed quite comfortable to write with - the pen feels very smooth with little to no scratch, and the ink glides on the page and dries instantaneously. The ink is also advertised as formulated to reduce feathering and bleedthrough, and I can confirm there is none. Now was this actually so much of an issue with Uni’s other pens that it warranted an entirely new product line? I’m not sure, but it doesn’t change the fact that the Zento is good.

Ink Comparison: Zento Black Ink (top) has a more matte look, vs. the glossy black Uni One (bottom). To draw a comparison to fountain pen inks, I’d compare the Zento ink to something like Platinum Carbon Black or Sailor Kiwa-Guro, while the Uni One ink is more of a glossy black like Aurora.

How Does the Uni Zento Compare to the Uni One?

As I noted, in addition to the Zento, Uni released the Uni One a few years ago, which was supposed to be another “specialty” ink that’s a step above your standard office gel pen. I’ve found the Uni One and the Zento to offer somewhat different writing experiences, so I can confirm the distinction is real. The One contains an ink formulated to be extremely dark (standard black) and/or vivid (other colors), with a glossier finish. So if you prefer a darker, wet look to your gel ink, you might prefer the Uni One, especially if you’re using the pen for drawing or doing layout work in a bullet journal or planner. The Zento seems better suited to pure writing, as it lays down a remarkably smooth line and, in my opinion, has the more comfortable barrel.

Takeaways and Where to Buy

Uni makes a great gel pen, and I surprised myself with how much I enjoyed the Zento as I don’t typically do much writing with gel ink beyond quick notes and annotations. I strongly prefer the barrel on the Zento over the One and pretty much any other standard gel pen - it’s got a nice balance, the perfect diameter for my hand, and on the standard model, a soft texture that’s comfortable over longer sessions. I will also say that the clips on both the Uni Zento and the Uni One are excellent - the wire design is highly functional - with the slight edge to the Zento as it feels a bit tighter on both the standard model and the Flow. That said, if you prefer the barrel on the One but want to try Zento ink, the Zento refills fit the Uni One, and vice-versa.

We currently have a large selection of the standard Uni Zento gel pens available in our shop, as well as a smaller selection of the Zento Flow, with the upgraded barrels. Zentos are priced at $3 and $11, respectively, with extra refills available for $1.75. You can get a nice pen at a reasonable price, or pick up a refill that will fit one of your existing Uni pen bodies.

You can tell the difference between the clip on a Zento (top and bottom) because it has the round holder, whereas the holder on the One is rectangular.

Diving Deep: On Exploring the "Back Catalog" of Established Brands

People frequently criticize established brands such as Lamy and Pilot for not introducing new products at a rapid clip, but what they overlook is the extensive back catalog of existing products that these companies have developed over decades, including dozens which don’t receive a lot of hype. Entire product lines have been ignored for so long that I was unaware of them despite nearly a decade as a blogger in the stationery world, and it was only after I opened a retail store and gained access to the full catalogs and pricing sheets that I somewhat shockingly “discovered” a treasure trove of great options that many people don’t know exist. These are excellent products that should receive far more promotion, not just by the community but by the manufacturers themselves. My observation is that most of these fall into three categories: multi pens (subject to the most egregiously unfair treatment), rollerballs, and mechanical pencils.

Multi Pens: “Tri Pens”, “Twin Pens,” and 4+1 Options

Is ignoring multi pens a U.S. thing? Did the proliferation of low-quality multi pens in the U.S. market during the 1980s and 1990s spoil the category for most people, outside of dedicated Japanese stationery aficionados? Apparently Lamy, Pilot, and Uni all have deep lineups of multi pens in their back catalogs, but with very little presence at U.S. retailers. I find this surprising given the enthusiasm among my own readership and customer base for multifunction pens, especially those slimmer models that take nonproprietary D1 refills. I took a flyer from Lamy on three multi pens that I had never used before: the Logo Tri Pen, the CP1 Multi Pen (both Twin and Tri versions) and the ST Tri Pen. All of these are exceptionally good, and I’ll call out the CP1 Twin Pen as my personal favorite of the three. The matte black finish and squared off clip are reminiscent of the Lamy 2000, and I like the slim design. Fun note: Gerd Müller, designer of my beloved Lamy 2000, also designed both the Lamy CP1 and ST series of pens. All of the multi pens take the D1 refill so you can customize them with the gel or ballpoint refill of your choice.

The Lamy Swift in the Special Edition “Black Forest”. Did you never hear about this one until a year after it was released? Me neither. I just got mine yesterday.

Rollerballs

Many people (including myself) had essentially written off rollerballs as overly wet, gloppy writing instruments that tend to bleed through every type of paper and offer very little variety in terms of writing experience. There are some excellent rollerballs out there, however, including the Ohto Ceramic Series (CR01 and CR02), as well as the underappreciated Lamy Swift retractable rollerball. The Ohto Ceramic Rollerball refill is one of the best “capped” rollerball refills I have used, and with modifications (i.e., a spacer) it can even fit into the Lamy 2000 Rollerball. The Lamy Swift is a retractable rollerball with a cool design feature: when you depress the knock to extend the refill, the clip retracts into the body of the pen. This not only gives you the comfort of a clipless pen - no clip digging into your hand - but it prevents you from accidentally sticking the pen in your bag or pocket with the tip extended (and ruining fabric).

There is no better $4 mechanical pencil than the TWSBI Pagoda. I’m confident of that.

Mechanical Pencils

Ok, so it’s probably not fair to say that mechanical pencils go “overlooked”. There are vibrant online communities solely dedicated to pencils (woodcase and mechanical), but for much of the stationery community mechanical pencils don’t receive a lot of attention. Personally, I think it’s because apart from the Uni Kuru Toga Dive, companies haven’t innovated all that much over the years, and most of the excellent mechanical pencils on the market have been around for a while. (In some cases since the 1960s, like the Pentel Sharp Kerry. If you’re interested, I did a review a while back looking at the Kuru Toga Dive and Sharp Kerry side-by-side.) In addition to the Sharp Kerry, check out the TWSBI Pagoda ($4, really?), and the gorgeous Pilot S20 at 1/4 the price of a Kuru Toga Dive, which is a great pencil but I would question whether it’s worth the current U.S. asking price.

And because I will get a dozen comments/emails asking if I don’t do this, the pens are, from left: TWSBI Pagoda, Uni Jetstream 4+1 Lite Touch, Uni Jetstream 4+1 Standard, Uni Jetstream Lite Touch 3 Prime, Lamy CP1 Twin Pen, Pilot Acroball 4+1, Pilot E95s fountain pen (because it IS underappreciated), Pilot S20 ballpoint, Pilot S20 mechanical pencil.

All of the pens and pencils discussed in this post are available to enthusiasts if you dig around enough, though sometimes U.S. retailers have to import directly from Japan, especially with some of the more uncommon mechanical pencils. While new product releases can be fun, I don’t get my stationery thrills from special and limited edition releases, but rather undiscovered (to me) gems that many people have been using as their everyday writers for years. Personally, I find many of the “innovations” in recent releases gimmicky, and would prefer to concentrate my efforts on raising awareness of existing products that are well made, that meet the needs of most people, and that I want to promote and support so that companies will continue making them.
