I really like these. They hold your page without falling out if you turn a book over and shake it. It's only meant for holding one or two pages, it can't handle much more than that, but I would't want it too as it would make getting it off harder. Unfortunately, I couldn't use this for what I'd bought it for. I had wanted to use it for my Bullet Journal, but they are so thick that the journal doesn't close properly. You might mark one page at a time with just one, but you can't mark multiple pages with them. I decided to just use post-it flags for that. The other problem is that they aren't marked on one side, so if you mark your line where you stopped reading, when you come back you have to guess if you stopped on the front  or the back of the page! So, I put star stickers on one side of them so I can tell what page I was on. Not terrible, but a little annoying. Overall, I like them and would buy them again. I really like the colors too!
