The tall sippy cup is an ideal next step when your little one is ready to move on from a cup with handles, as it has soft, comfortable grips. The leak proof valves release pressure and can be removed for thorough cleaning. The larger capacity of this cup makes it ideal for use at home or on the go. All Oxo cups feature dimples in the lid to ensure little noses have enough room and translucent walls to show how much is left inside. Recommended for children 9 months. Top rack dishwasher safe. The Oxo system transforms as your child grows as all Oxo cup parts are interchangeable, so you can mix and match as they gain confidence.. Green
