Features: Reusable & Eco-friendly: The picture hanging hooks can be carefully removed from the wall to be recycled. This not only makes them an environmentally friendly choice but also provides cost savings, as you can reuse them for future hanging needs. Minimal Damage: The sturdy, sharp-pointed nails used for hanging pictures won't cause significant damage to the wall. They only leave a very small hole, making them suitable for wooden walls, plaster walls, and drywall, but not for concrete or ceramic walls. Wide Application: The 20 lbs and 30 lbs hangers are perfect for hanging lightweight items such as small pictures, portraits, paintings, mirrors, keys, clocks, and kitchenware. The 50 lbs hanger hooks are suitable for heavier items like larger mirrors or paintings. Organized Storage: The picture hanging hooks kit comes well organized in a storage box, preventing the hooks and nails from being in a mess and ensuring easy access. Easy Installation: The picture hangers can be easily fixed on the wall with just a hammer. The top bulgy design protects your fingers from being knocked while installing the hook.
