The Build Bonanza lego compatible tape does not stick to anything. Grandkids were very disappointed and so was I. I would like to get my money refunded but do not have the receipt anymore. We tried several surfaces, walls were clean and smooth. It will lay down on the coffee table but what fun is that? They wanted to build lego figures up and down the wall. So far we have not found anything it will stick to and I am not a happy grand ma. I would like to have my money refunded. WE have four rolls and not a one of them will stick to anything we have in our house. The sticky side is just not sticky.
