For effective damage-free hanging indoors, use Command Clear Decorating Clips with Clear Strips. They hold strongly to a variety of surfaces including solid, hollow and painted walls, as well as other materials including wood, tile, metal and glass. They're easy to apply and remove, leaving no holes, marks or sticky residue. The clear hooks and strips blend in seamlessly, making them suitable for any room in the house or office. Rehanging them is as easy as applying a Command Clear Refill Strip, so you can take down, move and reuse them again and again.
