Yamamoto Ro-Biki Note Covers and Refills Compared

TRAVELER's Notebook vs. Yamamoto Ro-Biki: What's the Difference?

July 9, 2025

Since I’m becoming something of a notebook system specialist (Check out our new resource here!), I sometimes get questions about how the different systems compare to one another. While the Traveler’s Notebook is the most widely known “tall narrow” notebook format, there’s another option out there: The “Ro-Biki Note” series of notebooks from Yamamoto Paper. Online photos can create the perception that these two systems are related and/or interchangeable, and that’s not necessarily the case. Here are a few key differences:

The Ro-Biki canvas cover is actually more of a wrap. It ships with a velcro strap that not only closes the cover but also allows you to secure pens and other accessories in the outside pocket.

  • Different Measurements. While both Traveler’s Notebook and Ro-Biki are the same height (8.25”), the Traveler’s refill notebooks are roughly 4.25” wide, and Ro-Biki notebooks are 3.75” wide. This means that Ro-Biki notebooks will fit in a standard-size Traveler’s Notebook cover but a Traveler’s refill will be too wide for the Ro-Biki canvas cover (unless you trim the Traveler’s refill down).

  • Different Paper. Both brands use excellent paper that works well with a wide range of writing instruments - including fountain pens. Traveler’s Company mostly uses Midori MD paper for its standard refills (both companies share the same corporate parent), while also offering a wider range of options including watercolor, sketch, and ultralight Tomoe River paper. For the Ro-Biki notebooks, Yamamoto has chosen a soft cream-colored paper that I’ve seen identified as either “Chiffon Cream” or “Soliste” (which is one of the select papers in Yamamoto’s latest round of A4 packs). Again, both brands use good paper and this will come down to personal preference.

  • Different Build/Aesthetics. Traveler’s Company uses a cord-based system to hold the refills inside a basic leather cover that closes with an elastic band. The Ro-Biki is a bit more unique, in that Yamamoto has commissioned a cotton canvas cover that incorporates a zippered case and pockets along the outside. If you enjoy the Ro-Biki paper and notebook dimensions, you might find that the Ro-Biki also offers more built-in functionality out of the box, though this comes at the expense of customization. Those looking to avoid leather might also prefer the Yamamoto option.

I might take a Ro-Biki to the beach next week, since I can take it to the pool and down to the water without worrying about water getting splashed on leather.

Sorry, some of my writing had to be blurred here, for personal reasons.

Ro-Biki notebooks attach to the canvas cover by sliding the back cover of one notebook into a pocket, and then attaching additional notebooks to the “anchor notebook” using two supplied rubber bands, which are very thin and unobtrusive. Oh, and can we also get a shout-out for reticle grid? It’s one of the more underutilized rulings, IMHO.

Regardless of which stationery pouch I’m carrying, I have post-it notes, stamps, and document flags with me.

Takeaways and My Personal Thoughts

Traveler’s Notebook and Yamamoto Ro-Biki Note are different products that I suspect will appeal to different users. Traveler’s Notebook is more of a truly customizable system/system techo, while I’d characterize Ro-Biki as a notebook with a bit of built-in functionality in the canvas cover (which may be perfectly adequate for many users). Update: I’ve published a YouTube demonstration of me setting up the Ro-Biki, plus a size comparison with the Traveler’s Notebook.

Personally, I love Yamamoto’s Soliste paper, and I’ve enjoyed using one of the Ro-Biki reticle-grid notebooks for testing. This was enough to make me grab one of the covers for myself, as I already have Soliste hole-punched in my Plotters for general writing and the Ro-Biki Note paper has the same soft feel to it. (I’d love to confirm whether these are indeed Soliste notebooks - stay tuned.) Whatever paper it is, it’s handled all my inks quite well, and it makes me want to keep writing with it.

As of today, we have Yamamoto Paper Robiki covers and Robiki-Note notebooks in stock, and of course we continue to offer the full Traveler’s Notebook lineup and the new similarly sized Lochby Voyager Journals. Come see us in-store this week, starting tomorrow and Friday from 1-6, and Saturday from 10-6. Next week (July 13-20) we will be on vacation so get your shopping in before then!

Time to Pick a New Personal Journal: Maruman Mnemosyne Hardcover A5 Journal

July 2, 2025

It's time to pick a new notebook! This weekend I finished a personal journal (an Atelier Musubi bank paper A5, bound in soft fabric), and while I enjoyed my time with it, I was ready to move on. The Musubi Journal itself was an exceptionally well made book: The binding and cover held up well over the course of nearly two years, despite a fair amount of travel in my briefcase alongside laptops, pen cases, scissors, sharpened pencils, and who-knows-what-else. And while I find bank paper quite ink friendly, it's never been my favorite paper for everyday writing. Hand oil can cause problems with skipping and feathering on the lower half of a page, and for my personal journal, I don't want to worry about always having blotting paper or a calligraphy smudge-guard handy. So the next choice for an everyday notebook/journal was always going to be something more no-nonsense.

Whenever I choose a new notebook, planner, or journal, I run the risk of paralysis-by-analysis. As expected, I found myself overthinking this decision, so (late) last night as I was leaving I walked out of my office into the main shop area and pulled a Maruman Mnemosyne A5 Hardcover journal in mint green off the shelf. I've been excited about these Mnemosyne journals since I first saw them at last year's NY Now and have been looking for a way to get one into the rotation. (We won't talk about how long it actually took Maruman to get these things to the U.S. market.)

I love a good pre-printed Table of Contents. Especially one that is long enough to use as a true index. Which you will need on a 250-page notebook.

So why did I choose this notebook?

  • Reliability. Mnemosyne paper works well with all inks + pencil, with decent dry times, no feathering, and very little bleedthrough. The paper in the journal is a step up, at 90gsm instead of the typical 80gsm in the Mnemosyne spirals and the 70gsm in the Maruman Basic notebooks. While I don't really push paper all that much in notebooks that I use as personal journals - I’m writing, not testing inks - I've had no issues with any fountain pens that I've used in my first few days of writing.

  • It's "Just a Notebook." The Mnemosyne journal looks nice, but at the end of the day it will appear, to the non-stationery-addict eye, indistinguishable from your typical Moleskine, Leuchtturm, Anecdote, Endless, or other similar A5 hardcover with an elastic closure. The fact that I have a dozen just like it sitting outside the door to my office and a few more in my personal stash removes the block you sometimes feel when you have a really nice notebook that you’re hesitant to use because you don’t want to mess it up.

  • Table of Contents. In the Musubi, I made the rookie mistake of not reserving pages for an index or table of contents. The Mnemosyne does that for me, with a four-page table of contents that allows for 21 entries on each page. Whenever I finish a notebook, I go back and flip through to highlight pages with ideas I want to remember and possibly develop further elsewhere. The table of contents will let me do that in real time as I work through the notebook, or during my close-out review after I finish. The pages are also pre-numbered for easy reference.

  • Open Layout with Lots of Paper. This notebook contains 239 numbered pages (including the TOC) - a lot of paper for a journal in this style. The ruling is a .5mm dot grid. For bullet journalers and those who like to create their own charts and layouts, Maruman has included markers in the margins that you can use as guides. I probably won't use this particular notebook as a bullet journal or other homemade planner, but the functionality is there. You also have two ribbon bookmarks and the standard kraft paper envelope attached to the back cover.

Takeaways and Where to Buy

I'm only a couple of days in, but so far this Mnemosyne journal is exactly what I needed, and importantly, exactly what I expected from Maruman in terms of no-nonsense quality and functionality. If you're looking for a hardbound dot grid notebook in the classic A5+elastic style, this version is fountain pen foolproof and should last you for the bulk of the year, depending on whether you're a daily journaler and how much you write each day.

Available from most Maruman retailers, including our own shop, the Mnemosyne Hardcover Journal comes in black, navy blue, grey, and mint, and is currently priced at $39. While the price would seem higher than similar notebooks, this notebook has a noticeably higher page count (240 pages vs. the usual 190-200), and of course you get the Mnemosyne quality. The most remarkable aspect of this entire release is Maruman's decision to release Mnemosyne products in colors other than black. For me, the mint is clearly the winner, and I'd love to see a darker green, like they used in the Kleid x Mnemosyne collaboration. The newer A5 flex cover notebooks included a white version, but I could see that getting pretty dirty over the course of a year.

Come see us in-store! As noted above, we have the journals shown here, the rest of the Mnemosyne lineup, and more. Note that we have special hours on July 3rd and 4th. Saturday hours of operation will be per the usual 10am-6pm.

The Mnemosyne (bottom) is a thick notebook with lots of paper!

Notebook Review: Nina Cosford Sketchbook and Rediscovering Blank Notebooks

May 18, 2022

I’ve never been a huge user of blank notebooks, always opting for at least a dot grid, which to me offers a good balance of flexibility with some minimal structure for notes. As I mainly use my stationery for taking notes or journaling, I’ve never really needed a “sketchbook,” per se, but I do keep one or two blank notebooks lying around to test pens and inks, especially with crazy nibs. When Nina Cosford, a well-known illustrator based in the U.K., reached out and asked if I’d like to review her sketchbook, I was in the middle of a “make-an-inky-mess” project and thought this looked like an intriguing thing to review, even if it’s a bit outside-the-box in terms of what I normally write about. I’m glad I took this particular project on, as this sketchbook features excellent 100gsm paper that I plan to use frequently going forward.

The Nina Cosford Sketchbook as a Project

As I mentioned above, Nina Cosford is an illustrator and lifelong sketchbook enthusiast, who, unable to find that “perfect product” - something we can all relate to - set out to create her own! The result is this roughly 7” x 9” sketchbook that contains 80 sheets of plain, slightly off-white 100gsm paper bound in a softcover vegan cover with a red elastic band. (I would compare the size to the “F2” Midori MD Cotton notebook, maybe slightly smaller.) It’s a simple, understated working sketchbook that feels durable and contains excellent paper. You can read more about Nina, her work, and the process she went through in developing this sketchbook on her website.

This slightly off-white paper shows off shading nicely!

As you all know, I usually work in fountain pen ink, so when I tested the sketchbook my biggest concern was how well it would perform without bleedthrough or feathering on very wet nibs. I shouldn’t have worried - Nina Cosford is a Caran d’Ache ambassador who works in marker and other media that requires quality paper, and this sketchbook held up very well to whatever I could throw at it. The paper shows off ink properties quite nicely, including shading and shimmer.

This sketchbook uses a 100gsm paper that feels coated, so it resists feathering and bleedthrough. You would really have to layer the ink on in order to get this paper to bleed, especially since it was designed to work with marker.

Takeaways and Where to Buy

I really enjoyed trying out this sketchbook and can definitely see myself using it in the future for ink testing and drawing/doodling with pens, inks, and other media. Honestly, I’m trying to expand my repertoire to include more creative journaling, since I feel that all I do is work lately and I really want to get back to playing around with my stationery “just for fun.” You can purchase the Nina Cosford Sketchbook directly from her website, priced at $16, which is quite reasonable given the quality. If you enjoy sketching or journaling in mixed media, and especially if you enjoy using fountain pens or markers, this sketchbook makes for an excellent option whether you use it for art or writing or both.

I was provided this sketchbook free of charge, as a review sample. I was not otherwise compensated for this review. The Gentleman Stationer is supported entirely by purchases from the T.G.S. Curated Shop and the T.G.S. Patreon Program.

Notebook Review: The Theme System Journal

February 26, 2022

In these early morning hours, I’m struck by the thought that I should most likely be writing in my journal instead of online writing about journaling, but thus are the perils of stationery blogging! I will say that it’s much easier to build a morning or evening journaling routine , especially at first, when you have a quality personal journal with some, but not too much, structure. That’s where the Cortex Theme System Journal shines.

Built around concepts discussed in the “Yearly Themes” episodes of the Cortex podcast, the Theme System Journal offers “a simple framework for daily journaling”, allowing you to adapt it to your personal themes and how you choose to track your own individual needs and goals. While I won’t go into the intricacies of the “Theme System” in great depth, it’s built around the concept of planning for and organizing your year around broader “themes” instead of more traditional “goals” or “resolutions”. That’s not to say that you can’t have specific goals or resolutions within the context of each “theme,” but the idea is that themes are more adaptable as the year goes on, allowing you to adjust and stay on track even if a particular goal or resolution doesn’t work out. it’s an approach I’ve taken over the past couple of years, as reflected in my "Intentions for 2022” series of posts that I published around New Year’s Day. To learn more about the Theme System, check out the Theme System website or give the Cortex Podcast a listen. But you don’t need to do an intensive study of “the system” to find the journal useful as a stand-alone product. Its layout is fairly intuitive and I could see use cases beyond personal and professional development journaling.

Theme-System-Journal-Theme-Page

Layout and Functionality

The notebook is broken down in to several different sections, including four “Theme” Pages where you can develop your Annual/Quarterly/Monthly themes; 90 daily journal pages, though these are undated so you can journal more or less frequently should you choose; 12 “Daily Theme Pages” that allow you to track specific tasks/habits/guideposts or anything else that you might like to follow on a daily basis; 13 pages for notes; and two pages for an index. The version that I currently have is from the first run, which does not have the blank pages for notes, just the theme, journal, and tracking pages with the index template inside the back cover.

I hope you understand that nearly all of my journaling themes are highly personal and/or work-specific, so I won’t show you actual pictures of the journal in use here, but I can tell you that I find the layout to be both intuitive and flexible, Again, you can check out the Theme System website for actual examples of “themes” and how one would incorporate them into the layout if one were strictly following the system.

What I will do is show you how I’ve chosen to use the daily journaling page, which consists of four unlabeled boxes. I use the first box for short gratitude journaling, or briefly noting things I’m thankful for or which made me happy that particular day. The second is for a quote that I found particularly interesting or inspiring, since I’m trying to read at least 30 minutes every day. The third is my “anything” box, where I typically recount a few of the day’s significant events and how they relate to my annual themes/intentions. Finally, the fourth is a short box where I try to summarize how I’m currently feeling about things in a single word or short phrase.

I’ve been using the Tracking Pages mostly for general habit tracking, as opposed to anything specifically theme-related.

I’m honestly not sure what I would use the index for, so it will probably remain blank. I tend to journal chronologically, though I assume that if I ever wanted to organize my journaling by highlighting those entries that touched on a certain subject, I could use these pages.

Specs and Build Quality

Whether you use it for Theme System-style journaling or not, this is a great notebook built around functionality, and was originally developed in collaboration with Studio Neat, makers of the Panobook and Totebook. Like the Totebook, the Theme System Journal has a similar soft cover featuring a debossed Cortex logo, a lay flat thread sewn binding, and Munken Lynx 100gsm paper that so far has handled every fountain pen and every ink I’ve used in this notebook. I’ve heard that others have managed to make this paper bleed and/or feather, but no matter how hard I’ve tried, I have never experienced any issues. For functional everyday journaling, this notebook is more than adequate.

As you can see here, the Theme System Journal is only slightly smaller than the Nanami Seven Seas Writer.

The Theme System Journal is what I call “A5-ish” size, meaning that it’s slightly smaller than a standard A5 but not so much that it won’t fit most A5 notebook covers. I have had success using my Theme System Journal in both an A5 Roterfaden Taschenbegleiter and a Lochby Field Journal (pictured here).

Takeaways and Where to Buy

Two months in, the Theme System Journal has taken hold and I can see this as a long-term replacement for the A6 Hobonichi Techo, which I used for years before I found myself wanting something with just a bit more structure and space to write. Do I journal every day? No, I have mornings where I’m just not inspired, but I would say I’ve stuck with it a solid 5/7 days through the first two months of the year.

You can purchase the Theme System Journal directly from Cortex Brand, with orders fulfilled via Cotton Bureau. The Theme System Journal costs $25 for a single notebook, but you can save $5 if you purchase a subscription, which will ensure you get a notebook each quarter. While there have been stock shortages of the Theme System Journal in the past, I understand that supply issues are now resolved.

I purchased the Theme Journal featured here with my own funds, for my own use. This post does not contain paid third-party affiliate links, and I was not otherwise compensated for this review.

Stálogy Paper: My Thoughts, Two Months In

September 22, 2021

You can’t really evaluate a new paper until you’ve used it regularly for a couple of months, and since July I’ve been putting a Stálogy notebook through the wringer as my daily work notebook. I’ve never used this paper before, and I can see this brand easily forming a part of my daily rotation going forward. If I had to sum up Stálogy in a single sentence, it would characterize it as extremely thin, versatile Japanese paper that makes a great daily driver or work notebook, especially if you value quick dry times. That said, if you’re looking for thin paper to showcase pooled ink like Tomoe River, this may not be the notebook for you. While Stálogy doesn’t feather, and the ink looks great on the white paper with the grey ruling, you may see limited pinpoint bleed through with wider nibs and/or wetter inks, as thin, absorbent paper has its limitations.

(You may recall that I wrote a piece back in July discussing how you can customize notebooks by cutting them down to size, and that’s exactly what I did here. Stálogy notebooks don’t come in “Traveler’s Size,” - I made this one myself so a half-year version would fit in my Standard Traveler’s Notebook.)

Stálogy notebooks don’t come in “Traveler’s Size,” - I made this one myself so a half-year version would fit in my Standard Traveler’s Notebook.)

Stálogy covers come in a range of colors other than black, including yellow. light blue, and red versions.

Style and Build Quality

I love the Stálogy aesthetic. The flexible leatherette cover feels sturdy without adding unnecessary bulk to the notebook, which would only detract from the key selling point of paper this thin. I’ve been carrying this notebook in my briefcase or car on a daily basis for two months (albeit in a Traveler’s Notebook cover), and so far the binding has held up well.

The Stalogy pages feature grey rulings with a header allowing you to label the month, day, and date.

The other thing I am truly enjoying is Stálogy’s light grey, 4mm grid ruling. Those who find bold rulings obtrusive, but who are still looking for more structure than a blank notebook offers, should give the Stálogy system a try. The grey lines essentially disappear under your writing, and 4mm is a great size for those of us who write small.

Every two lines are subtly numbered along the left-hand margin of each page, providing a 24 Hour layout for scheduling and logging.

Layout and Performance

In addition to the minimalist, almost industrial “leather book” aesthetic, people love Stálogy for the subtle date/time layout in the header and margin, allowing you to use this notebook for notetaking or journaling, or as a planner. The left-hand margin is subtly numbered 1 through 24, for a full 24-hour layout if you want to use your notebook as a planner or log book. Across the top, you can select the month, day, and date, which is always useful, no matter what your use case might be.

A handful of writing samples on Stálogy paper. As you can see, the ink looks great on the white paper with grey ruling, and I had absolutely no feathering even with some very wet pens.

Which brings us to the big question: what about the paper? It’s quite good. That said, paper is all about trade-offs. Those who love really thin paper know that in order for a thin paper to handle a lot of ink without feathering or bleed-through, you typically have to coat the paper and accept a longer dry time. Stálogy takes a different approach. This paper is more absorbent than something like Tomoe River, so you have a (much) shorter dry time. (Several friends who are lefties LOVE Stálogy for this very reason.) The paper also has a nice texture that lends a pleasant, tactile feel as you write. The trade-off might be some slight, pinpoint bleed-through with wet inks and wider nibs, though most fountain pens still work very well. While I absolutely did not experience anything that would keep me from using this notebook as a daily driver, I am overly cautious in labeling something as “fountain pen friendly” because that’s become a loaded term that has different meanings for different people.

The reverse side of the same page. You see some slight “pinpoint” bleeds on especially wet writing samples (i.e., stubs and ebonite feeds with wet ink), but nothing that prevents me from using this paper all day, every day. For how I use paper, the quick dry time is absolutely worth the trade-off in a work notebook.

Takeaways and Where to Buy

With future availability of Tomoe River Paper in question, the focus has turned to other options for extremely thin paper that allows notebook makers to pack a high page count into a compact size. While it’s not absolutely “ink proof” like Tomoe River, Stálogy paper is a very good alternative, especially for those of us who need a thin notebook and value more absorbent paper with better dry times. Personally, I’ve been using Stálogy every day for the past couple of months and love both the paper feel and quick dry performance.

My favorite color? The light blue (though the yellow really pops).

Stálogy notebooks are available in a range of sizes, including A5, A6, and B5, in both “365 Days”/“Year” (368 Page) or “180 Days”/”Half-Year” (192 Page) versions (also referred to as “year” and “half-year”). Currently, the T.G.S. Curated Shop stocks the A5 notebooks in both 365 and 180 Days, with the grid ruling. Dot grid is also available, which I hope to stock soon. In addition to the classic black cover, Stalogy has released brighter pastel versions, such as the light blue shown here, as well as periodic special editions. Half-Year notebooks are priced at $20, and 365-Day versions at $28.

The T.G.S. Curated Shop is an authorized retailer of all brands sold, including Stálogy. For more information on paper recommendations, I would check out this post on “Fountain Pen Friendly Paper” and how I categorize different brands.
