Command Clear Window Hooks deliver damage-free hanging for decorating your windows. Clear design allows them to disappear when they're up and disappear when they're down. Each hook holds strongly and removes cleanly - leaving behind no marks, sticky residue or stains. UV-resistant strips of adhesive are designed for indoor and outdoor use. Each hook holds up to 1/2 lb. Set includes three durable polycarbonate hooks and four UV-resistant, clear strips.
