These are great for hanging posters. It even hung really heavy posters. The only problem we had was when we pulled them off. The ones where we pulled them down just like the instructions said to came off just fine. But, my husband pulled one directly out instead of down and it pulled the paint off the wall. I would definitely buy them again, but you just have to be careful to follow the directions exactly when you pull them off.
