[Product Information]

Made of plastic and steel.
There are 5 sizes and 37 hooks in total in a plastic container, with 1 plastic tool to fix the hook and 1 liquid tool to balance the hook.(plz refer to the pictures on the left and you know exactly how they work)
Best for plaster wall, would definitely recommend if you have wooden, hard, concrete, brick or reinforced walls.
Forget the drill & screw routine. Just a few taps with a hammer on a cement or block wall, and you can hang up your picture, keys, umbrella, clothes, mirror, photo frame- or even potted plant, clock, wall art and other life necessities you want on my walls. That's how strong these picture hangers are.
When you remove any hook, the small holes will be "nearly invisible" but they likely will be far less noticeable than a standard nail. They don't tear up your walls or leave holes like hard wall nails and they easy to remove if you need to reposition a picture.
