Command™ Micro Hooks are an innovative solution for hanging light-weight objects such as calendars and keys securely and damage free. They hold strongly and remove cleanly using 3M stretch-release technology. For effective damage free hanging indoors, use Command™ Micro Hooks. 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. Command™ 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
