Don't Peel. Don't stick. The absolute worst. I can't even tell you how much time I wasted with these tiles. First off, you can't peel the backing off without destroying part off it to get a wrinkle into the plastic. Once you get a wrinkle into the plastic, you might get it to peel off if you are lucky. But really it doesn't matter, because once you get the backing off, these DO NOT STICK TO THE WALL. I ended up using glue on a large majority of these, and pulling down the few tiles that stayed stuck to glue them as well. I pray they hold up after all of that work. This is total garbage. Do not buy. They should pull these off the market. They look pretty, but I spent far more time installing these "time saving tiles" than I would have installing normal tile.
