The OXO Tot Transition Soft Spout Sippy Cup with Handles, Opal, is smarter than the average toddler drinking vessel. The OXO Tot Transitions Soft Spout Sippy Cup features a patented almond-shaped spout that only opens with light suction, so it won't leak when dropped or thrown. That means less messes for parents to clean up. The removable handles and interchangeable lids from the Tot Transitions line make this cup versatile, while the comfortable shape encourages little ones to serve themselves. Measurement markings help track progress, while the hinged cap protects the spout and prevents spills on outings. The cap and spout come apart for thorough cleaning in the dishwasher. With its tough design and clever features, this sippy cup helps make everyday living with tots a little easier.
