This hook is not metal. This hook does not make Rainbow loom a little more complicated than bracelets. This hook is not solid at all, he broke after less than an hour of use. This hook was delivered two months after the order. NOT WORTH ANYTHING THIS HOOK !!!!! ESPECIALLY DO NOT BUY !!!!! I am very unhappy with this. This really is the m **** made in China and shipped individually from Hong Kong (bravo for the ecological impact!).
