Chew on this.

The new Bite Proof Sippy has an ultra-durable yet soft spout that won’t tear when it meets even the most tenacious of teethers.

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. Munchkin even backs this no-leak promise with a 100% replacement guarantee. Secured, and rest assured – this might just be the training cup of your dreams.
