Product Information The Command Medium Matte Black Hook pack is part of the Command Decorative Hooks collection, which provide you with a variety of styles and colours to choose from. The Command Medium Matte Black Hooks use the revolutionary Command Adhesive, allowing the hooks to hold strongly to surfaces such as paint, wood, tile and more. As with all Command products, they come off cleanly, leaving no holes, marks, sticky residue or stains. Reusing the hooks and moving their position again and again is really easy too, simply apply a Command Refill Strip to the back of the hook when you want to place it in another location.
