Glass Sip & Straw Cup

This Sip and Straw glass cup does double duty. First use it with the silicone sip spout as a glass sippy cup and then when your child is a little older replace the silicone sip spout with the silicone straw, and then you will have a glass staw cup. As an added bonus there are handles that can be attached to the bottle or removed (if you prefer).
