Ideal for hanging wreaths, signs, thermometers, or other seasonal decorations directly to the outside of your window. Using a formulation of the revolutionary Command adhesive, these outdoor hooks are specially designed to hold strongly outdoors. They are water resistant, UV (ultraviolet) resistant, and can handle temperature extremes from -20 F (degree Fahrenheit) to 125 F. Like all Command products, they remove cleanly with no marks or sticky residue so you can use them over and over again.
