I use all the command products when I go camping. They don't harm the walls of our camper and I even use them outside the camper for my thermometer and welcome sign and to hold the lights up. I wouldn't use any other products to hang or hold stuff. Not destroying my walls or leaving marks is very important to me because everything looks new and not old if I take one of the hooks down. I recommend these products to every relative and friends I know. Thank you for a wonderful selection of products.
