I purchased these Amor Present 42 count Wall Climbing Ninjas for my nephew who's 4 because I thought he would like them and he loves them. He wanted to open all 42 but my sister would only allow him to have ten at a time. He's been having such a fun time with these sticky ninjas which makes me happy as he lives far so I don't get to see him so much. I attached two pictures the first one is my sisters ceiling which is pretty funny the second is my nephew putting them on the wall. These are really great especially for the price they work great and any kid would have tons of fun with them.
