Adhesive Hooks From mysonder - Set Of 8 Hooks - Easy To Install And Remove - Strong & Durable Plastic Material - Money-Back Guarantee (Office Product)

These things are really cool. I haven't been able to use them, my son stole them. But his room is now decorated with things hanging all over the place. He's happy, so I'm happy. Great product.
