"I absolute love having cute little key chain characters hanging from it with my keys. However, the sticky adhesive for the wall/LEGO was not strong enough to hold multiple keys and fell off the wall. Followed all the instructions for cleaning the wall. It just didn’t stick. I’d recommend you don’t even use what comes with it for adhesive and just go get some 3M backing. Cost me like $1.99 and now it can hold up to 7 pounds."
