MarumanMNEMOSYNE Notebook 9.92 x 7.05 Inches (B5), 5mm dot grid, 80 Sheets (N104), White

TLDR: These are absolutely top of the line notebooks, particularly with fountain pens. In dollars per centimeter of line, the 194 (B5) size is a 14%-20% better value than the 199 (A4) size at current prices ($14.85 for the 199 and $10.04 for the 194).Maurman notebooks are first class. To date they are my favorite of all I have tried. Other top-tier brands I have tried are Rhodia A4 size and Clairfontaine A4 size, which are also excellent, but for a variety of reasons I prefer the Mnemosyne. Fountain pens write like a dream on this coated paper, as do gel pens. The thickness and feel of the paper is amazing. The subdued dotted lines are really nice. The cover is fantastic and the rear cardboard of the 199 or rear plastic of the 194 is substantial. The micro-perforations tear off super smoothly. Also, when you remove the entire page from the notebook before removing the micro-perf scrap, the little nibs stay attached to the page and you don't end up with nibs all over the place. Lastly, the off-white color is classy and archival looking (if you want bright white paper, look elsewhere). Everything about these notebooks is premium. I do wish that they contained more pages. The 199 has 70 sheets (140 sides) and the 194 has 80 sheets (160 sides). Personally, I think that 100 pages would be a better number. But for some reason, all premium notebooks tend to have between 50 and 80 pages. I guess it is a European / Japanese thing.I am currently really geeking-out on fountain pens and paper and have compiled a ridiculous amount of information comparing the different notebooks I like the best. One of the things I have calculated is value for the money. I am not thrilled about how much these quality notebooks cost, so I wanted to know how I could maximize my value. With this in mind, I calculated the number of line-centimeters the 199 and 194 have. Doing the math reveals that based on the current prices of these notebooks, the smaller 194 gives you 14% more value than the larger 199. Of course, this doesn't consider the aesthetics of the size differences. With the 194 you are writing on a smaller piece of paper, will have more "carriage returns" than the 199, and your hand will encounter the side edge and binding edge more often. The 194 is more compact and easier to carry, though. Also, the 194 has plastic on the rear cover instead of cardboard.So, I can't say which format you will prefer, just that in terms of pure value per written word the 194 comes out on top."BUT WAIT," you may say, (well, at least I did), "isn't it likely that with the smaller paper and having to carriage-return more often, there might be some inefficiency involved in coming to edges that may weigh in favor of larger pages where your writing flow isn't broken as often?" To me, this seemed like a likely thing. It seemed somehow intuitive that the more often you had to break to go to the next line, that there would be efficiency losses. So I set out to test this theory, to see if the 194 was truly more cost effective.Well, it turns out, for me at least, my theory was exactly wrong. Not only wrong, but OPPOSITE wrong. When I wrote long lengths of text on both the A4 paper and B5 paper, trying to maintain my exact same writing style, size and spacing, I ended up getting MORE text into the same overall length of line in the smaller notebook. I was shocked. What happened is, as much as I tried to make my writing the same size and spacing in each notebook, my brain didn't let me do it. Somehow, when I was writing on a larger page my writing expanded. And when I wrote on the smaller page it constricted. Looking at the pages side by side it was obvious. Crazy. I honestly thought I was writing the same. So, as it turns out, for ME, the 194 is not 14% more efficient than the 199, but actually 21.6% more efficient (i.e. cost effective). Of course, your mileage may vary. But for me the 194 is a better value.All of that said, I still vacillate between the 194 and the 199. I like the smaller size of the 194 for carrying, and the fact that it has 80 instead of 70 pages. I think I also prefer the plastic back of the 194 over the cardboard of the 199. But if I am being honest I have to admit that I like writing in the 199 more. It just so much more spacious. My ideal notebook would be the 199 with 100 pages. At the same price as the current one, of course.

I recently had the pleasure of using the Maruman MNEMOSYNE Notebook in the A5 size (8.27 x 5.83 inches), and it has quickly become an indispensable part of my daily workflow. As someone who values high-quality stationery for both professional and personal projects, this notebook exceeds expectations on multiple fronts.Superior Paper QualityThe first thing that stands out is the exceptional paper quality. The pages are smooth with a subtle texture that provides just the right amount of feedback when writing. Whether you're using a fountain pen, rollerball, or pencil, the ink or graphite lays down cleanly without any feathering or bleed-through. This is especially appreciated by those who use both sides of the paper and prefer a clean, crisp appearance for their notes or sketches.Thoughtful Design and LayoutMaruman has put considerable thought into the notebook's design. Each page features a subtle grid pattern that's perfect for writing, drawing, or charting without being intrusive. There's also a header space at the top of each page for dates or titles, aiding in organization. The minimalist aesthetic is professional and elegant, making it suitable for meetings, classes, or personal journaling.Durable and Practical BindingThe notebook employs a sturdy twin-ring spiral binding that allows it to lay completely flat or fold back on itself, providing flexibility depending on your writing surface. The binding is durable, ensuring the pages stay secure even with frequent use. Additionally, the pages are micro-perforated for clean and easy removal, which is perfect for sharing notes or detaching pages without leaving a jagged edge.Portable and Convenient SizeThe A5 size strikes an ideal balance between ample writing space and portability. It fits comfortably in most bags and backpacks without adding bulk, making it convenient to carry around for on-the-go note-taking or sketching. The lightweight yet sturdy cover protects the pages without weighing you down.Versatile Use CasesWhether you're a student, professional, artist, or writer, this notebook adapts to various needs. I've found it invaluable for meeting notes, brainstorming sessions, and even quick sketches. The high-quality paper enhances the writing experience, encouraging more frequent use and creativity.Excellent Value for QualityWhile it may be priced slightly higher than standard notebooks, the Maruman MNEMOSYNE offers superior quality that justifies the investment. The durability, paper quality, and thoughtful features ensure that you're getting a product that enhances productivity and lasts over time.Final ThoughtsIn a market flooded with generic notebooks, the Maruman MNEMOSYNE A5 stands out as a premium choice for those who appreciate quality and functionality. Its exceptional paper, smart design, and durability make it a worthwhile addition to anyone's stationery collection. I highly recommend it to anyone seeking a reliable and elegant notebook to elevate their writing or creative projects.

Very smooth writing, love the layout. High quality, flat-lying spiral notebook with exceptional paper.

Solidly made with durable paper. Recommended.

The absolute best notebook. The pages are nice and thick, pens glide on them and don't bleed through. I love using calligraphy pens and they go great. The lines are light grey and visually appealing instead of the ugly blue and red traditional college rule. No worries about imprints on the next pages. It also fits a lot of text.I have several gorgeous notebooks that sit unused because this one is just perfect. I have super long lists and notes to write every day and it fits a lot on one page. It's spiral bound, which is perfect, because so many notebooks aren't for some reason. It's way more comfortable to write like this. Pages are easily torn out. I just wish there was more fun colors of it!

This is a solid notebook. It feels sturdy, the perforations are nice and clean making tearing off easy, and I quite like the way the page is divided up with space at the top for date and topic.HOWEVERIf you are left handed, don't even think about using a gel pen, or a pen where the ink isn't quick drying. The paper in this notebook is very smooth and does not absorb ink quickly, so there is almost a 99% chance you will smear unless you wait a bit for the ink to dry before continuing writing. I wanted to use a dip pen with a quick dry ink, and even that still smeared, and have resigned myself to using a Micron felt pen instead to write in this notebook
