DARUMA is a wooden tooth hardener with a safe and gentle design that fits the size of your baby's hand. It is made of hard wood (maple wood) that is safe to gnaw and lick, so you can play with it as your baby's first toy. You can hold and nibble wherever you want, and when you shake it, it makes a rattling and pleasant sound. You can also put a string through the hole above and hang it on a buggy or mother bag. (String is not included, please use a safe leash that suits your child)
