Big enough Keychain (6 cm long and 5.5 cm wide), soft plastic, and rather well done, with the effigy of Eisenberg. It is of a thickness of 3-4 mm and in any relief. Material gum before, smooth plastic back. I do not think so big, but ultimately it's just as well, we identify it easily and it is not bulky either. It's a small pleasure that I made to my husband who is a fan of Breaking Bad. Usually he does not like keychain, but there he was hooked immediately ;-)
