Reportedly, Tomoe River is about to go the way of all flesh. Honestly, it's not the end of the world - there are plenty of other very good fountain pen papers out there - but for TR fans now is the time to grab it while it lasts. So here's some in a handy package at reasonable price.
Endless manufacture in India, and they do it will; crisp edges and a really classy sewn binding. The book isn't enormous - a bit smaller than A5 - so the 'large' claim is perhaps a touch ambitious, but there's plenty of paper for most note-taking purposes at least. It lies flat without protest, too. So, fill your boots indeed... but don't tarry too long.
