Outdoor Medium Window Hooks-Clear
At this time I am very pleased with this product! I am using them as a replacement to suction cups used on my recreation room/attached garage, interior side of windows as hangers for my star-shaped lights that I've had for several years now. Even though I rub a bit of vegetable oil on the suction cups before putting on windows, eventually the oil will have served its purpose and the cups will release from the windows causing my lights to fall.
I have faith that this will not occur with the 3M Hooks, but I will certainly let you know if it does.
