These are my favorite inserts. Tomoe River paper is truly in a class of its own when it comes to fountain pens in particular. The thinness of the paper means you won't be adding a lot of bulk to your notebook.
As a bonus, the pages are perforated. This doesn't interfere with writing in any way, it's very subtly done and you can write right over the nearly invisible line. It's nice to have the option.
