Coco QuizonToday
Comes in a variety of sizes, spine folds flat, paper never bleeds but pages are a bitch and a half to tear out so you must live with what you have written.
My favorite is the B6 Slim, A5 and for when I’m really inspired the A4 notepad version. Available in dot and grid, I also think it comes in blank but I’ve never personally come across it. The flagship store in Tokyo is also a sight to behold.
