New Arrivals: Pilot S20 Ballpoints AND Mechanical Pencils!

May 27, 2025

The Pilot S20 Ballpoint Pen is one of my favorite new discoveries, and we are now happy to offer the matching mechanical pencil as well so that you can make a matching set. Featuring Pilot’s deep red and deep brown wood finishes, these are not only attractive writing instruments but highly functional as well, with a slim silhouette that fits comfortably in the hand and will also travel well in a notebook pen holder or planner loop.

The Pilot S20 Ballpoint Pen takes the Dr. Grip-style “Cocoon” refill, and the mechanical pencil takes standard .5mm mechanical pencil lead. In addition to restocking on the Pilot S20s, we have additional stock of the Uni Jetstream SXR-600 Parker-style ballpoint refills, as well as the SXR-200 Universal D1 refills for your D1 multi pen of choice.

Our brick and mortar will be open this week from 1pm-6pm Thursday and Friday, and from 8am-11am on Saturday. (Reduced hours due to a personal conflict.) We will likely have some additional hours Sunday afternoon which I will post later this week.

Workhorse Pens: Pilot S20 Ballpoint

January 22, 2025

The T.G.S. “Workhorse Pen” series is where I park all of my recommendations for those pens that I personally rely on to get work done. While this series started out as exclusively focused on fountain pens, as my interests have become more eclectic over the years, I’ve expanded the series to cover other categories - namely low-viscosity ballpoint pens.

While the low-viscosity ballpoint pen received its own writeup as a category, I wanted to take a moment to highlight an exceptionally good take on the product: the Pilot S20 ballpoint pen. The S20 has been around for a while, in both ballpoint and mechanical pencil format, though like many of Pilot’s best products, distribution has been largely limited to Japan. Featuring Pilot’s “Acro-ink” (the Acroball refill in a Dr. Grip-style cartridge), the S20 stands out due to its unique shape and feel in addition to the excellent writing experience.

Four different low-viscosity ballpoint pens (well, almost) that I use regularly. From left: Pilot S20, Uni Jetstream 4+1, Anterique Mach Ball in Clear Green, and the Caran d’Ache Infinite 888, which is not technically a low-viscosity ballpoint but has an exceptionally good refill. .

I won’t belabor the benefits of low-viscosity ballpoint ink, because they aren’t necessarily specific to the S20 and I’ve already written about them fairly extensively. To briefly recap, low-viscosity ballpoints are sometimes referred to as “hybrid gel” pens, meaning that they feature smoother ink flow than your typical oil-based ballpoint, while maintaining the faster dry times and increased permanence. The downside? Color selection. I’ve not seen many hybrid ballpoint pens come in colors other than black or blue (and sometimes red and green), as opposed to gel pens, which these days are available in pretty much any color you can think of.

The combination of the gently shaped section and the tactile wood used in the Pilot S20 make for one of the most “usable” pens I’ve experienced. It’s honestly the first pen in a while that just makes me want to pick it up.

Why do I love the Pilot S20 so much? For starters, both the top and bottom halves of the pen feature a concave hourglass shape, which allows it to rest comfortably in my hand. While “feel”, “balance”, and “comfort” are highly subjective, in that they often depend on variables like hand size and writing pressure, I personally consider this one near perfect. The wood barrel gives the pen a tactile feel, making it one of those pens that’s a pleasure to pick up simply because it feels elegant - almost extravagant - despite only costing $25.

The Dr. Grip “Cocoon” refill.

As for Pilot’s “Acro-ink”, to me this refill feels more gel-like than the Uni Jetstream or the Anterique Mach-ball refills, which have a more tactile feel akin to a pencil. Part of this might be that the S20 comes in a .7mm tip size, but I’ve always felt that Pilot Acroball pens lay down a darker, wetter line than their counterparts. This pen is a very smooth writer, so much that I’ve recently started using it for journaling - something I can’t say about other ballpoints in my rotation.

Takeaways and Where to Buy

Since I got my hands on the S20 last year, I’ve not taken it out of my personal rotation. The red and black version sits in my Plotter A5 pen loop, and has become an everyday planner pen for me. The brown and black version lives on my writing desk at home. While the Dr. Grip is marketed as Pilot’s “ergonomic” everyday pen, I tend to find it slightly too large. The S20 better fits my own hand and writing style, while keeping the same excellent refill.

For writing samples, I used standard Target-brand copy paper, since that is how many people have to use their ballpoints at work, school, and otherwise out in the world. Of the three shown here, I think the Pilot Acroball ink is the darkest, followed by the Anterique Mach Ball, and then the Jetstream. All are very good and I use them interchangeably.

As of this week, we have the Pilot S20 ballpoints back in stock in our shop. We sold through our initial shipment around Christmas, but have plenty once again. A few of you have asked about the mechanical pencil version, and the .5mm is on the way as soon as our supplier has it back in stock. (.3mm will depend on interest, so let us know!) The S20 ballpoint is priced at $25 and comes in two colors: Red/Black and Brown/Black. Additional refills are also available. I’ve checked, and these are indeed the same cartridges that fit the Dr. Grip pens sold here in the states, though these are .7mm “Fine” refills whereas most U.S. Dr. Grip pens are sold with the 1.0mm “Medium”. Personally, I prefer the fine, and will likely try to swap one into my Dr. Grip Full Black to see if it gets more use.

New Arrivals: Ballpoints and Multi Pens to Kickstart Your New Year's Productivity

January 21, 2025

I had a bit of a surprise Monday morning, when an unexpected delivery from Japan arrived. (Somehow I must’ve missed the shipment notification.) Included in this first big delivery of the New Year was a restock of the excellent Uni Jetstream 4+1 Multi Pens in three colors, Sage, Blue Grey, and the new “Beige”, as well as the orange and blue Karimoku collaboration finishes.

Fans of muted earth-tones like beige and sage will love the Uni Jetstream 4+1 “Bamboo” series.

We also received more of the exceptionally good Pilot S20 ballpoints, which I’ve enjoyed so much I’m working up a “Workhorse Pen” post highlighting what I consider one of the best low-viscosity ballpoints out there. Featuring Pilot’s “Acro-ink” in a Dr. Grip-style refill, this .7mm ballpoint writes a smooth, dark line, and features a contoured wood barrel that will appeal to many pencil fans as well as ballpoint enthusiasts. Finally, we’ve received the ballpoint version of the Mini 5-friendly Pilot Birdie, so you can complete the trifecta set (pictured at top).

I’m trying very hard to get the matching mechanical pencils, which apparently can be difficult to source.

Come visit us in person! Public hours are Thursday and Friday from 1-6pm, Saturday from 10-6pm, and otherwise by appointment. We look forward to seeing you this week!

New Arrivals: Pilot S20 Ballpoints, Uni Jetstream Prime and Edge, and More Giftable Ballpoints

November 26, 2024

Ahead of the holidays, one of my top priorities was to restock our supply of higher-end ballpoint, rollerball, and gel pens, especially Japanese imports, but we also made room to bring in some new finds. Last week, we received our first shipment of the excellent Pilot S20 ballpoint, which uses Pilot’s hybrid “Acro-ink” and performs similarly to the Uniball Jetstream. A friend from our local pen club gifted me a S20 last year, and I couldn’t get over how comfortable this pen was to use: it sports an hourglass silhouette and soft, polished wood finish in two striated wood grains: red/black and brown/black. We also have a healthy supply of the Dr. Grip “Cocoon” refills, which is that cartridge that fits the S20.

Other new arrivals include the Pilot Birdie/Birdie Switch: a small format writing instrument from Pilot that comes as either a mechanical pencil or “reversible multi-pen”; as well as additional stock of the Uni Jetstream Prime, the Uni Jetstream Edge, and the Zebra Sarasa Grande Vintage. All colors and tip sizes should be restocked and showing as available.

The hourglass shape of the S20 ballpoint simply fits very well in your hand!
