Practical Design: The curved hook can be more firmly hanging small objects. The downward nail forms an Angle with the wall, allowing it to hold the wall more firmly,Easy to Install: The Pin Hooks are very easy to work for drywall or wooden wall, but not apply to ceramic wall or concrete wall. Push in gently with your bare hands or a hammer,Durable Material: The picture hanging hardware is made of zinc alloy. They are stronger and more durable than plastic nails. The nails only leave a very small pinhole in the wall.,Wide Application: Three color combinations. You can easily hang small objects such as keys, picture, paintings, towels, kitchenware, necklaces, folded umbrellas, or decorative lights,Convenient Storage: The kit comes with a transparent box big enough to hold 30 hooks. You don't have to worry about them getting lost or disorganized. (Keep out of reach of children.)
