## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for lefties and taking notes at a computer.
*by  on Reviewed in the United States April 13, 2026*

These are great little notebooks meant to used with the spiral at the top. It's a bit unconventional but works well when taking notes at a computer. Works well taking notes anywhere, but they do better than other options at a computer.Paper has proven to be fountain pen friendly, and still good for pencils or other pens. It's very versatile and I have no complaints.

### ⭐⭐⭐⭐⭐ The best notebook for DIY dashboard creation
*by  on Reviewed in the United States December 22, 2024*

Sometimes I get overwhelmed and prefer to plan my various activities on a single grid page, and this notebook is excellent for that. With a landscape format and the spiral on top, I don’t have to worry about the binding getting in the way. The back is sturdy, and the paper quality is excellent — though it’s worth noting that the grid only appears on one side, and the back of each page is blank. For me, this is a bonus, since I can draw on one side and plot on the other. Very receptive to all varieties of ink with no ghosting. Le Pen, Sakura Micron, fountain pens, stabilo fine tipped markers, and prismacolor premieres all work amazing. The squares are a good size for creating trackers of different kinds, or doing landscape design while physically standing in a yard (the hard back helps with that, too). The price point is also great; it’s rare to find a notebook less than $20 that doesn’t remind you that you compromised to save a few dollars every time you write. Instead, this feels like a steal.

### ⭐⭐⭐⭐⭐ Worth every penny--and then some.
*by  on Reviewed in the United States May 7, 2016*

I cannot praise this notebook enough.I'm a math major, and I take all of my class notes with the Mnemosyne Inspiration. The paper itself is exquisite, and takes everything I've ever thrown at it without a hitch, from .5 mm pencils to 2mm color pencils from .25 gel pens to broad nib fountain pens. It loves everything you can imagine using with it. It especially loves my Waterman Carene pen, which is the deal-maker (or breaker--depending on how a paper does). The pencil lines erase and erase and erase if I make mistakes--which I tend to do a lot of, since parabolas and I seem to hate each other (but not hyperbolas--go figure).For math, this notebook simply cannot be beat. Going back to portrait notes is a major PITA after using this notebook's landscape orientation for a day or two. When I go back to normal notebooks, I miss the Mnemosyne's title bar at the top that lets me log quick-reference information about the contents of my notes--chapter/section, topic, date, etc. I miss the subtle tick mark in the center that lets me know where I can split a page if I need to. I miss how I have enough real estate to write some of my complex problems all the way across the page, where I can see it all, rather than trying to wrap it around to another line, like typical American paper usually required. Or how I can write a formula to one side, notes about how it works in a block below it, then a sample problem in yet another box, and a graph in yet another box. I miss how everything is on one page in a form that makes sense to me. I miss the perforation that works right, every single time, always tearing out the notes without catching or hiccuping at all. I even miss how I can draw out diagrams on the blank page on back or cut out printouts from my professor and glue-stamp them to the blank page on the back and have it facing my homework so that I don't need to dig through massive notes over and over again. Or how I can use that blank page simply to doodle during a dull moment in class.If you love brainstorming your notes, then this notebook will be your new best friend.If you're more restrained and want to do standard I. A. 1 type notes, then you can do them with this notebook, too.When this notebook really shines, though, is when I'm sharing information with a study group. Everyone can see my information and make sense of it at one glance. All I need to do is turn it to face them, and all of the important info is there in one place, and easy to read.Yes, this is an extremely expensive notebook, but it's a steal when I think about how much better of a math student it has made me.I don't know what I'd do without this notebook.
