I love these! They work best on flat surfaces and have the strength of a small suction cup or magnet. Their adhesion is great, but they remove without leaving any residue. Best of all, they can be rinsed off and used over and over again!I've used them on whiteboards, mirrors, windows, walls, doors, metal, plastic, ect. Obviously they can't hold a ton of weight, but are perfect for displaying kids art on the fridge, notes on the door, small signs on windows, ect. I've used them to secure glass knick-knacks on shelves and I've even used them in my fridge to hold plastic charcoal packs on the wall.I've had a couple holding a plastic suncatcher on my skylight (which gets horrible condensation, moisture, direct sun, and cold) but it's still going strong 4 YEARS LATER! Hasn't fallen off a single time even though it's upside down so gravity definitely has the advantage (suction cups would only hold for a week).Seriously I love these things!!!
