SAKAE Technical Paper Paper Notebook, A6, Squared, Soft Cover, Tomoe River FP, 2.4 oz (68 g), Cream 160P, TMR-A6NB-68HC...

Great pocket-able notebook! The 68gsm Tomoe River paper doesn't feel as smooth as 52gsm but it still is able to show off sheening and shading pretty well.

With water-based fountain pen ink or, I suspect, water-based markers, there is zero bleed-through. You do get some ghosting, which is to be expected. However, an alcohol-based marker will blast right through the paper and onto one or two pages behind it. So... the paper is great for water-based media, but unsuitable for alcohol-based media. I still love the notebook, though. It's sturdy, nicely soft-cover bound, and the paper has a feel to it that is almost velvety without being textured or toothy. I do recommend this product, with the caveats as above.

I bought this specifically to swatch my fountain pen ink so it would show off all the beauty. I am very pleased with this notebook. I honestly dont know why I waited so long to purchase this type of paper.

I've tried all the major fine notebook & paper brands such as Leuchtterm, Clairfontaine, Moleskine. Tomoe River paper is probably the best I've found. But do look for this 68 GSM paper because some of their papers are incredibly thin like old airmail paper. But they all have the essential qualities you want for a fountain pen ink. Basically no bleed through, no feathering. Because this paper is extremely smooth the ink doesn't soak in so it can still take a while to dry, especially with broad or flexible nib wet writers. The cream color is just beautiful. The A6 size is sort of pocketable but a little bit on the wide side. (Compare to a pocket Moleskine in the photos.) One thing I don't like about this notebook is the corners are square edged so they feel sharp and will get ragged if you put them in and out of a pocket with any regularity. Black cover is very attractive but makes it pretty much impossible to write a label on the spine or the cover. The manila colored notebook in the photo is also a Tomoe River paper notebook larger that solves these issues, I wish they made it in a similarly small pocket size though. In that photo I actually cut the corners off the black notebook with a sharp exacto blade.
