My husband has a large collection of baseball hats and they drive me crazy as for they lay everywhere around our house. I saw these hooks in our local supermarket and thought they would be the perfect organizational solution for these hats! I rushed home and followed the instructions, I prepared the walls (cleaning them and letting them dry) before peeling the adhesives and sticking the hooks to the wall. Sadly, over the next two weeks I lost one hook after another....until only 3 of the 12 hooks remained. Needless to say I was extremely disappointed! Additionally, small bits of paint/plaster stuck to the adhesive backings. I will not buy this products again.
