This paper is so thin the ink bleeds through terribly. I read all the other reviews that say exactly that but I thought maybe it would be different for my fountain pen. Not so. I suspect that even rollerball pens would bleed through the thin paper. Beautiful journal though. The whole thing is kind of flimsy -- it's definitely not a hard cover. The spine itself is pretty stiff so the cover and pages don't really fold down very flat. If you're looking for a large journal you can roll up and you use pencil or ball point this might work well.
