For effective damage-free hanging indoors, use Command Designer Medium Hooks. These classic design hooks 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 hooks blend in seamlessly making them suitable for any room in the house or office. Rehanging them is as easy as applying a Command Refill Strip, so you can take down, move and reuse them again and again.
