The Maruman Mnemosyne N195 Special Memo Notepad, like its other Mnemosyne siblings, is a notebook that easily makes the cut for replacing your standard Moleskine notebook. Sure, it's spiral-bound, but you'll probably be able to forgive that once you try the paper.
I've always enjoyed the N196, which is the same format as this notebook except that the spiral binding is on top. While that's a great format for some purposes, I also enjoy using a side bound notebook as well.
It's easy to compare this notebook to the top-bound brother because they're very similar. The sizes are a bit different, where the side-bound notebook is A5 and the top-bound is B6, and the former has 80 pages instead of 50 like the top-bound book. But, the same paper is used in both, which is the real star.
The N195 is an example of a "perfect notebook" for my use. I love the A5 size pages for most purposes, and it's one of the biggest things I consider when looking for a new general purpose notebook. This one fits the bill nicely with dimensions of 6 x 8.25 inches and 7mm ruling. The ruling spacing hits a sweet spot for me. It's not too small, but it still works well with my small-medium writing style.
