tough, not the cheap hard plastic kind
My wife loves them. After wasting money on the cheap hard plasticy types, these are the matte almost delrin like material which are much more durable than the typical brands. For those who aren't sure what that is like, then I'd say it's comparable to composite plastic. So far. pur 3 yr old threw them and dropped them and not one tooth broke off yet.
