Here's a shot of it on top of the Tar Callion 8.5 x 11 journal made with HP Premium 32 paper. The Kunst & Papier dimensions are an odd 8.25 x 11.75. You can also see the difference in paper color. The K&P is a nice off-white.
I don't like writing into (or out of) the "hump" so I need something that will lie flat when open:
The hardbound journal contains 112 pages of 100gsm alpha cellulose paper with a paper toothier than the slick Clairefontaine or HP Premium. It can accommodate my .5mm cursive italics, but if I use any pressure it starts snagging some of the nibs. Round nibs are no problem, but you will feel the difference between this and the smoother papers. It's a good, useable paper for me even though it's not ideal (Zerkall Book Smooth comes close to that).
The paper is fountain pen friendly, and that's what counts. Although HP Premium is very smooth, I don't like the way it absorbs a bit of ink and broadens the line. The K&P paper (like the Exacompta paper) is very ink friendly and preserves the thins and peserves the crispness of your writing. No print-through or feathering either! Here's a closeup:

I'm going to continue using these. Actually, the next volume of my journal will be on a Kunst & Papier Binderboard sketchbook. It's the same paper except more (144 pages vs. 112) and cheaper ($15.99 vs. $18.99). But I'll report on that when the time comes. For now, I'm a happy boy.
