Munchkin Bite Proof Sippy Cup

Finally, a bite proof cup that's gentle on soft gums, because while a spout should be tough, it doesn't have to be hard. Munchkin's new Click Lock™ trainer cups come with a soft, bite proof spout and a 100% leak-proof guarantee!

These innovative cups feature a simple locking lid that closes to create a leak-proof seal. You can see, hear and feel the cup lock in place, so you have triple assurance against dribbles and drips.
