The Pilot Iro-Utsushi Dip Pen (and in General, Simple vs. Fancy Dip Pens)

October 1, 2025

This past weekend I did a post on ink swatching, and walked through how I create the ink swatches that I use both for the shop and to organize my own personal ink collection. Like most people with a lot of ink to organize, a key component of my ink swatching kit is a dip pen. Because I’m a writing enthusiast with an interest in the calligraphy and art sides of things as well, many of the pens that I personally use are on the more expensive side - particularly my glass pens and Drillog metal dip pen.

But what if I told you that an $8 alternative exists, and that in many ways this other pen is just as good and will serve you well for basic ink swatching and even some writing and journaling where you might want to switch up your inks mid-session and don’t want to fiddle with emptying or refilling fountain pens? That solution is the Pilot Iro-Utsushi Dip Pen.

I chose the fine since most of my other dip pens range from medium to double-broad.

The Pilot Iro-Utsushi is a very basic product: a standard dip pen with a stainless steel fountain pen nib (fine or medium) attached to it. This pen differs from a calligraphy dip pen in that the nib is tipped for writing, and it can’t be swapped out of the holder. While some might find this “limiting,” I think that’s the point and what makes this product special: it’s intended for one thing, which is writing with fountain pen ink.

Dip Pen Tools in Holder on Desk

While I’m not sure I’ll ever make the Iro-Utsushi a “core tool” in my repertoire - I have way too many fun glass pens to reach for - I see no reason not to have one, since it’s an excellent option to have within reach for travel, meetups, and quick writing samples.

As I mentioned above, you can use the Iro-Utsushi for both ink swatching and standard writing. In my last post, I mentioned how I like to keep small sheets of “micro swatches” that are more portable than full-size swatch cards. This dip pen would be perfect for that, especially in the fine nib. And it offers a nice experience for standard writing too. Despite the lack of a feed, the underside of the nib holds a fair bit of ink and I regularly get 3-4 full lines of writing with the fine nib version. While the holder is a bit narrow for my hand and therefore may not be especially comfortable for longer writing sessions of a page or more, that’s not something I’d typically do with a dip pen anyway.

Takeaways and Where to Buy

I don’t have any problem saying that the Pilot Iro-Utsushi is one of the best basic dip pen options on the market to use with fountain pen inks. Whether you’re a glass pen enthusiast looking for a less-fragile option to take to meetups or away from the security of your desk, or just someone looking for an inexpensive option to finally finish swatching and categorizing all of your ink samples, it’s hard to do better than the Iro-Utsushi, especially at the price point.

And, yes, I know that some of you have probably heard the internet rumors from the Japanese market that the Iro-Utsushi is being discontinued, but other intel has suggested that Pilot is merely releasing new colors and the pen will continue to be offered, at least in the U.S. market. Pilot is a bit different than many Japanese pen companies in that they continue to offer certain products in the U.S. (i.e., the E95s fountain pen) even after they are discontinued in Japan. Stay tuned, but I’m not panicked on this one yet as I can still get them here.

You can pick up a Pilot Iro-Utsushi dip pen in our own shop, starting at $8, in a range of clear acrylic and wood finishes. Nibs come in fine or medium, but note that not every color available in both nib options.

My Favorite Ink Swatching Tools and Techniques (Yes, I'm Becoming a Glass Pen Person)

September 27, 2025

With the dozens of different colors we stock in the shop and the 100+ bottles in my personal collection, ink swatching and indexing becomes critical because you quickly forget what colors look like, and the color swatch on a bottle label can be inaccurate. Since I found myself working on new shop swatches this morning, I thought it might be fun to talk about my personal swatching process and some of the tools I use.

I had to add ink swatches of the recently released Colorverse Colorvent “Top 3” inks from last year’s Colorverse Colorvent Calendar, and thought it might be fun to document the different techniques used.

Each ink swatch that I do (for both the shop and personal collection) has two components: (1) a darker “swab” that showcases different tones in the ink as it pools on the paper, and (2) a writing sample. My format hasn’t really changed much since the early days, but my tools have evolved. I currently have three main setups and techniques that I use, depending on my mood and the type of ink that I’m working with.

Primary Setup: Glass Cocktail Stir + Dip Pen (Glass or Metal)

For most inks, I use a glass cocktail stir to create an ink swatch, and then a medium-to-broad nib dip pen for the writing sample. The actual writing sample is the most important for me, since I generally use pens for work or personal journaling and I like to see what the ink will look like on the written page with my everyday fines and mediums. As discussed above, the ink swatch is used more to see the underlying tones, which will come out in wetter nibs like broads and stubs.

Many thanks to Lisa at Olive Octopus, who tipped me off to the glass stir technique! She also recently did a post on her own ink swatching tools and techniques, and comes at things from a different perspective as she sketches a lot and also uses brushes and water to bring out the different ink properties.

I have a couple different dip pens that I love, but my current favorite is this broad glass pen by Glass Studio Aun that I picked up at this year’s San Francisco Pen Show. Up until recently my tool of choice was the Kakimori brass nib - which is still a great option that allows for plenty of line variation - but that was before I had written with a really nice glass pen, and to be honest this broad glass nib makes everything else feel like writing with a nail on a chalkboard.

Alternative Setup No. 1: Folded Nib Pen

If you have an ink that benefits from having a LOT of ink on the page, you can choose to do an ink swatch or writing sample with a folded metal nib. These can be a lot of fun to play with if you enjoy highly stylized writing that will not necessarily result in clean lines. (The “splatter effect” is a feature, not a bug!) I enjoy using folded nib pens when I’m doing a full-on ink review, not just a simple swatch, and I’ll do a full page of writing on multimedia paper and really get a sense of how the ink looks when it’s REALLY wet, especially those inks with heavy shimmer and sheen.

Colorverse “Pulsar Pulse,” a super sheener. You can do an ink swatch card with a folded brass nib, but it’s much harder to write smaller text. That said, folded nibs can really bring out the sheen in super sheening inks simply because they apply a LOT of ink in one stroke.

Alternative Setup No. 2: Plotter + Drillog

While larger card-sized swatches are often the most practical, especially for comparing colors under washed-out fluorescent lighting in pen shops and pen show hotel ballrooms, I also like to keep a second set of swatches for personal use in one of my Bible-sized Plotter binders. Most of these are what I internally think of as my “micro swatches”: small color swatches followed by a writing sample that are portable enough to carry with me for quick comparisons. For these, I’ve been using my recently acquired Drillog .5mm dip pen. As I mentioned in an earlier post-San Francisco Pen Show Post, the Drillog 2.0 fixes many of the issues with the original Drillog, including issues with consistency of ink flow and smoothness. I’ve found this to be an excellent ink swatching tool and can see myself using it for most of my personal ink samples going forward.

A Note on the Ink Swatching Paper

For my ink swatches, I use two papers. The first is Col-o-ring Paper made by the Well-Appointed Desk, which is sold in a wide array of convenient formats that can also be trimmed down or adjusted to however you would like to store them. The cards shown here are sold as part of a set with card holder pages and a Bible-sized Binder, which is what I use in the shop because without the plastic sleeves the swatches tend to smear from so many different people handling them. For my personal ink swatches, I typically use Midori MD Cotton Paper, since it’s my preferred paper for personal writing and I like to see my ink samples on paper I use on an almost daily basis.

The TGS in-store ink swatch album. Yes, we sell these. They are made by Papier Plume. The ink cards included with the album set are Col-o-Ring, though you can also use the Iroful paper cards.

Fountain pen ink preferences are highly personal, and swatching is no exception. I tend to be a lot less strict in terms of things like format and technique than some people. For example, I have hundreds of ink swatches that I’ve accumulated over the years, many of which were not even done by me as they were gifts from friends, and none of them look the same and are on different-sized paper or even in a Rolodex. For my purposes, this is perfectly fine, but many prefer to have a uniform format that they can easily search. If you feel like sharing your technique, please do drop a comment or send a message.

Dip Pen Comparison: Kakimori Metal Nibs vs. Tom's Studio One-Dip Nibs

September 21, 2024

I’m far from an accomplished artist or calligrapher, but that doesn’t stop me from enjoying and messing around with dip pens! While most traditional calligraphy nibs aren’t intended to be used for longer than a month or so, as they corrode, over the past couple of years certain companies have focused on brass and stainless steel nibs that are more akin to glass nibs and lettering pens, in that they can be reused over the long-term.

From left, the Kakimori Brass Nib, the Kakimori Antique Brass Nib, and the Tom's Studio One-Dip Brass Nib.

The two receiving the most attention are Kakimori’s metal dip nibs (particularly the brass options) and Tom’s Studio’s relatively recent “One-Dip Nib”. Since I was in the shop all day yesterday and had some down time, I broke out my personal dip pens and started playing around with a few different inks to get a better sense of how these nibs compare.

A close-up shot of the Kakimori Antique Brass Nib, where you can see both the ink channels and the (very) sharp tip.

A writing sample with the Kakimori standard Brass Nib. I've done a couple different writing samples showing the line variation you can get with the Kakimori metal nibs - as you can see it's a bit easier to write sharper lines with the Kakimori, whereas the Tom's Studio One-Dip below lends itself to a more rounded script.

To start: I’ve previously reviewed the Kakimori metal dip nibs, so for a more specific analysis of how that nib particular nib works and how I’ve used it in the past, you should check out that review. While I haven’t fully reviewed the Tom’s Studio One-Dip nib on its own, I would describe it as more akin to a traditional “lettering pen” or “ruling pen”, which operates via a thumbscrew/dial that you use to open and/or close the ink channel to adjust how wet the pen writes. These pens are very different, and while I’m personally inexperienced with ruling pens and therefore still getting the hang of the One-Dip Nib, here are a few observations:

  • I’ve found the Kakimori nibs to be the most user-friendly and intuitive. They hold the ink in the channels that encircle the conical nib, and feature a sharper point that makes it easier to write a finer line with the pen held vertically. You simply dip the nib and go. The downside? I’ve found that the channels have a tendency to clog with heavier shimmer inks, and can be difficult to completely clean without something like a toothbrush. Certain free-flowing inks may also “blob” onto the page, and there’s little you can do about this, whereas the Tom’s Studio One-Dip nib lets you adjust the inkflow.

  • The One-Dip nib is probably the more versatile tool, especially for accomplished calligraphers, illustrators, and other artists who actually know what they’re doing, unlike yours truly. My main observation with this nib is that with very wet inks, you can control line width by turning the thumbscrew/dial on the side, which either narrows or opens the ink channel. Even the slightest of adjustments will give you variation, though the narrowest line I’ve been able to get with the One-Dip nib is still wider than what I can achieve with the point of the Kakimori. Writing with this pen is more akin to folded nib calligraphy.

  • Each nib lends itself to different techniques, especially outside of writing. For example, if you enjoy drawing, illustrating, or simply playing around with how ink behaves on paper, the Tom’s Studio One-Dip nib has smooth sides, which means that you can dab some ink onto the paper and use the rounded edges as a brush without flooding the page with more ink. It’s difficult to do this with the Kakimori nib, since the ink is stored in the channels on the outside of the nib.

Showing just a bit of line width/wetness variation with the Tom's Studio One-Dip Nib. Here, I've adjusted the thumbscrew to get alternately lighter and darker lines.

From what I've seen online, many people have been using the Tom's Studio One-Dip nib to draw and then brush/fill in their illustrations with color. For those who want to know, the inks featured here are three of my favorite Tom's Studio ink colors: New Forest, Mallard, and Loch Ness!

Takeaways and Where to Buy

As someone who primarily uses my pens for writing, I’ve been trying to introduce another layer to my enjoyment of this hobby by doodling/drawing more frequently, and as a result I’ve accumulated a fairly large collection of dip pens. In addition to drawing and some creative journaling, I also use these pens for most of my ink swatches, as they allow you to alternate between lettering and broad brush-like strokes of ink. I haven’t posted most of this - some of it’s really bad - but I find it fun, relaxing, and I’ll try to do a better job of sharing more in the future.

We currently stock both Kakimori nibs and Tom’s Studio One-Dip nibs in our own shop. As mentioned above, the Kakimori nibs come in brass, antique brass, and stainless steel finishes, and the Tom’s Studio One-Dip nibs are available in brass and stainless steel versions. We also have Kakimori-compatible nib holders in stock, though the One-Dip Nib requires a standard metal-clutch ring nib holder, as opposed to the rubber used by Kakimori.

New Arrivals: Midori MD Dip Pens, Stalogy Notebooks, and Laban Aphrodite Pink!

July 11, 2023

At customer request, we’ve also started adding some dip pens to the shop. The first to arrive are the Midori MD dip pens, featuring the same super smooth nib as on the Midori MD fountain pen. I’ve been using this pen to swatch inks, and am very much enjoying the hexagonal holder, which is apparently made from a blend of paper and plastic and has a unique tactile feel. The nib on this dip pen has a medium point, and it’s intended for standard writing/ink testing as opposed to calligraphy.

Stalogy Notebooks are also back in the shop, including the 2022 and 2023 limited edition covers in both 1/2-year and 365-day formats. Colors include, from left, Cream, Forest, Salvia, and Fog.

Finally, yesterday’s pleasant surprise was the arrival of a full box of Laban’s Aphrodite Pink ink, the perpetually backordered favorite color from this ink series! We now have a full restock of all colors of the Laban Greek Mythology Inks, available to ship immediately.

Is it a pink? Is it a red? Is it a “Brown Pink?” However you describe it, I absolutely love this color and it’s long been a go-to when I want to write with something interesting.

The Gentleman Stationer is an authorized retailer of all brands sold, including the brands sold here.
