People are always asking what is the best paper for fountain pen usage in their Notebook. Hands down my choice is Tomoe River Paper. If you have never written or drawn on it, you are missing out. I've only ever been able to experience it in my Hobonichi but now Taroko Shop is selling standard size inserts with Tomoe. The price is very reasonable as is shipping. The inserts were shipped in a protective sleeve between two sheets of hard plastic which protected them from bending. I also received a coupon, a personal note from the Shop (Steve) and two cool wire clips. The shop is currently sold out of these amazing inserts, but you can get them at Red Pen Travelers now (which is exciting for US customers especially).
I typically use
If you want to try a great paper, very deceptively light weight, that holds ink superbly, I strongly urge you to try Taroko Shop Tomoe River Inserts.
These inserts were purchased by me for my own use and evaluation.
