Tommee Tippee 3in1Cup, Insulated Convertible Cup From 18 months and beyond, your little one is learning important new skills every day, including how to drink like a grown up. Designed to grow with your developing child, the Tommee Tippee 3-in-1 Insulated Convertible Cup has a unique lid that allows you to choose whether they drink from the straw, sip straight through the lid or gulp from an open cup. The free-flow lid is small enough for your child’s mouth and helps them control their sips. Equipped with innovative anti-leak technology, the cup is completely leak and shake-proof when used with the straw, even when turned upside down or shaken. Our unique valve seals and regulates the flow of liquid to stop leaks and to ensure easy drinking. The cup can hold 300ml of cold liquid and has a double-wall insulated base to keep your child’s drink cool while they play. The entire sippy cup is BPA, BPS, PVC, Phthalate and Nitrosamine free, so you can rest assured your little one isn’t exposed to harmful materials. It’s also both dishwasher and steriliser* safe for extra peace of mind. The lid is also completely lockable to prevent any messy spills while on the go. Simply align the lid with the locked padlock symbol to ensure your cup is leakproof. *Our insulated cups are suitable for sterilisation by cold water table/liquid solution only
