They are miniatures and are not good for hanging heavy things, they are attached to the wall with a sticker. They're worth keys, caps. very light things. They're still pretty. They are made of flexible material.
Very, very, very healthy!! Solid enough, but bend like a thick silicone, completely odorless. Attached to a sticky layer, like kitchen hooks.
They are the same as in the photos, they have arrived before time and i like them very much i recommend
