Ask TGS: What's the Best Pen for a Planner? Slimmer Pen Options for Pen Loops

August 14, 2024

It’s August, which means that the annual “back to school and back to work” season has started for many. You know what else that means? Planner time! I’ve noticed two distinct times of the year when people tend to invest in a new planner or notebook system. The first is during the November-January holiday season, just before the new year, and the second is in August and September, when the summer vacation comes to a close and many people return to work and/or school. In addition to general inquiries about the best planner or notebook system that might fit their specific needs, I receive a lot of questions about pens and pencils that “fit” planners. Usually this means they are looking for a slimmer pen (or multi pen or mechanical pencil) that will fit the often narrow “pen loops” or “pen slots” built into notebook covers. Since I’m already thinking about planners and notebook systems given the classes I taught at the D.C. Pen Show earlier this month, the upcoming planner and techo-heavy San Francisco Pen Show, and my participation in the Chicago Planner Conference this November, I figured this is a good time to update my previous planner pen recommendations.

  1. Current Favorite Planner Pen Recommendation: Tom’s Studio Lumos Refillable Fineliner. Many people love fineliners and brush pens for their planners and notebook systems, and the Tom’s Studio Lumos allows you to refill this style of pen with your favorite fountain pen inks. The Lumos comes in three different format options: the Lumos Pro has a single tip, the Lumos Pro Duo allows you to have two different colors and/or tip styles in the same pen, and the Lumos Mini works well with smaller pocket-sized options. The slim format fits easily into most pen loops, notably the Plotter system. Read more on how the Lumos pens work here.

  2. Fountain Pen Recommendation: Pilot Capless Decimo. The slimmer version of the Pilot Vanishing Point is an excellent option for planners and notebook systems, especially when paired with an extra-fine nib for writing in tighter spaces. I will also note that for many, the slimmer Decimo body also solves the “clip placement” issue that people sometimes have with the larger Vanishing Point. Read our full review of the Pilot Decimo here (and no, I’m not selling my Harvest Yellow!)

  3. Multi Pen Recommendation No. 1 (Needle-tip Gel Pen): Pilot Hi-Tec-C Coleto. The Pilot Hi-Tec-C Coleto is a versatile tool perfect for those who enjoy color-coding their planners and/or notebooks, as you can hold up to four of the Coleto needle-tip gel refills in a single pen body (and even a pencil and eraser insert). The Coleto can also be a relatively inexpensive option for those who enjoy lots of colors - I sometimes carry up to three of these in my bag at any given time. I reviewed the Coleto quite a while ago and likely need to update my thoughts on what continues to be an excellent multi pen.

  4. Multi Pen Recommendation No. 2 (Flexible Option): Lamy 2000 Multi Pen. I say “flexible” because Lamy’s 2000 multi pen is marketed as the “Four-Color Ballpoint,” yet because it uses universal D1 refills, you can transform it into a gel pen, a gel+ballpoint+highlighter, or - as I do - an upscale Jetstream multi pen. You can read my full write up on this pen here and why it’s been a fixture in my rotation for nearly a decade.

  5. Ballpoint Pen Recommendation: Uni Jetstream Prime or Anterique Ballpoint. Many people prefer a simple black ballpoint pen for work. It’s reliable, professional, and most importantly, not distracting. For something like this, I will usually recommend a low-viscosity ballpoint that’s a hybrid between traditional ballpoint and gel ink, meaning that the pen will dry fast, and will neither smear, feather, or bleed-through thinner planner papers. Both the Uni Jetstream Prime and any of the Anterique pens feature a traditional slim “ballpoint pen profile” that slides easily into a planner and fits nearly all notebook pen slots.

Do you have a favorite planner pen? If so, please write in or drop a comment. These are just the five that I’ve relied on recently, and there are dozens of popular options that would also include the entire Fisher Space Pen lineup, the Lamy CP1 fountain pen, the Traveler’s Company Brass Pens, Baux Pens, the Zebra Sarasa Grand, and more.

Planner Pens: Picking a Pen for the Plotter

September 14, 2022

Brace yourselves, because as I hinted in my San Francisco Pen Show recap, a lot of notebook/system-Techo-related content is headed your way in the coming weeks. I thought I’d kick things off with a quick photographic response to the burning question that many of you have been asking via e-mail, DM, and in the blog comments: What pens fit the various Plotter leather pen loops?

Plotter A5 (bottom), Plotter Narrow (Middle), and Plotter Mini 5 (Top). If Plotter is reading, all I need now is a Bible Size and a Mini to complete the set (well, that and the “Square”). I promise I’ll figure out a way to use them all. (Maybe.)

Before we get started with pen comparisons, I need to do an overview of how Plotter works from a setup perspective. One of the key features of the Plotter system (which is either a benefit or a drawback, depending on how you like to purchase your planners), is that Plotter is completely customizable, meaning that you purchase the cover, refills, and all desired accessories separately to create the notebook that works for you. While the Plotter system does not ship with a pen loop, you can add one by purchasing the “Leather Penholder with Lifter” accessory refill specific to your size leather binder.

Pens that Fit Plotter A5, Narrow, Bible Size, and Mini Pen Holders

The product listing for the Plotter A5 penholder states that it will fit pens up to 13mm in diameter. The listings for the Bible Size, Narrow, and Mini penholder accessories indicate that they are supposed to be the same size as the A5, and since I personally own both A5 and Narrow-size Plotters, I can confirm that they are roughly identical. That said, these penholders are leather, so in real world testing, there is definitely variation in how tightly individual penholders are sewn, and the leather may stretch over time depending on the size of the pens that you keep in the loop. For example, both the Platinum Plaisir and the Nahvalur (f/k/a Narwhal) Original Plus fountain pens fit the pen loop on my Plotter Narrow, while neither came close to fitting the tighter pen loop on my Plotter A5. Here are several examples of how different pens fit, with pictures. (Narrow is on the left, and A5 on the right, with the exception of the Nahvalur that wouldn’t come close to fitting the A5.) If something fits both my A5 and Narrow “easily,” I can only assume it will work with most Plotters, except the Mini 5 discussed separately below.

Pens that Fit the Plotter Mini 5 Pen Loop

By far, I’ve received the most questions about my Plotter Mini 5, the smallest of the Plotters and the one I’ve been carrying as a combination wallet/pocket notebook. According to Plotter USA, the Mini 5 pen loop holds pens up to 9mm. As you might imagine, finding a suitable pen to fit this tiny notebook has been more challenging, and for the most part I’ve simply clipped a variety of pocket pens to the outside of the loop. (This technique also makes for quicker deployment - something I find advantageous for most forms of pocket writing.) To be honest, the only pen I’ve tried that actually fits inside the pen holder is the Kaweco Liliput, though it’s not pictured here because I don’t own one and borrowed one at pen club to test. Here are a few that I’ve actually been carrying in the Mini 5, all clipped to the outside:

Penco Perfection “Light”

Traveler’s Company Brass Ballpoint

Pens such as the Lamy Pico, Schon DSGN Pocket 6, and Kaweco Sport are too wide to fit inside the loop. I suspect the Fisher Space Bullet Pen might work, but don’t have one on hand to test.

Given that the Fisher Space Pen “Shuttle Pen” fits (even though it’s too long for actual carry in my pocket), I suspect the bullet pen will fit as well.

Takeaways and Where to Buy

This post isn’t intended to be comprehensive, but rather to provide examples of what pens fit the Plotter pen loops. As you can see, the A5/Bible/Narrow/Mini pen loop is fairly versatile, while the Mini 5 somewhat more restrictive. My experimentation, of course, is limited to those pens that I have on hand in either my personal collection or the shop. Your mileage may also vary depending on your particular leather pen loop and how aggressively you try to stretch it.

I’ve thoroughly enjoyed using my Plotters over the past few weeks, and it’s prompted me to undertake a relatively deep reconsideration of how I use my notebook systems and the role of notetaking in general. As I mentioned, you’ll be seeing more Plotter-related content soon!
