Wooden rattle with a bell inside. It probably smells like hinoki cypress, so I think it's made of hinoki (lol). My child used it until they were 1 year old, so they chewed on it, but it has been thoroughly cleaned! There is a feeling of use, so if you are concerned, you may want to refrain from purchasing! It's a natural wood toy, so it's safe for babies to put in their mouths! I'm waiting for your questions!
