They're easy to apply and remove - leaving no holes, marks or sticky residue. Rehanging them is as easy as applying a Command™ Refill Strip, so you can take down, move and reuse them again and again. Suitable for a wide variety of surfaces; solid, hollow and painted walls, as well as other materials including wood, tile, metal and glass.
