Helps transition from bottle to sippy... A nipple top for babies and a sippy for toddlers are both included. Removable handles (add the transition ring instead). Use it on-the-go... insulated and durable, even with the toughest toddlers!

This is a great piece, use it until the nipple shows wear then replace only that... Let's combat the 20 plastic bottles and cups in the cabinet-syndrome together.
