Outstanding quality. The Tomoe River Sanzen paper quality is amazing to write on, bringing out the best in the ink and nib. Hands down my favorite paper. Despite the 52 gsm, there is no ghosting, feathering, or bleeding, even when writing with a wet, broad nib.

The Best Journal I've Ever Had
I love my new Tomoe River notebook!! The paper has such a nice lightweight feel to it (and awesome drape), but is a total champ when it comes to stopping bleed and ghosting (even my heavier pens aren’t enough to make a noticeable impact on the readability of text on the other side of the page, it looks so clean!!). Fitting so many pages into such a slim notebook is a miracle too. The paper is doing a great job of showing off my shimmering inks, and figuring looks so sexy on this stuff. Altogether, I prefer it to the original Tomoe river paper (controversial, I know, please don’t hurt me :’) )! The lay flat binding is my favorite part of this notebook; this makes journaling so so easy, and I think should be a must on every notebook ever, haha. The cover, end papers, binding and even blotting sheet all feel premium! I love the hard black cover, kinda reminiscent of the Moleskine books, which I love the look and feel of. The only let down here is the ribbon, which feels a little thin and cheap for this level of notebook, but thats not a huge deal at all haha. Altogether, the best journal I’ve ever owned. How writing with fountain pens should be!! (Also always nice to get a handwritten note from Blake in the super premium feeling packaging :) )
