Buyer beware…looks cute but not doesn't hold up. The upper screw hole is blocked by the wire design. The only way to install the screw is to put it in at an angle or use an offset screwdriver.
Metal is black and sturdy and easy to install. The hook itself is very sturdy. They are sturdy decorative and a beautiful addition.
These hooks are basic hooks that come with hardware to install in drywall. Great for hanging chimes and also my bug zapper. Works perfectly for my outdoor plants and solar hot air bal.
