Smarter (and tougher) than the average sippy cup, the 6 oz. OXO Tot Transitions Soft Spout Sippy Cup, Opalhas a silicone spout that conforms to babys mouth for a comfortable sip and less mess. Plus, the hinged cap closes to create a leakproof seal and protect the spout when not in use. The removable handles provide a comfortable grip for your little one, and the cap and spout are removable for easy, thorough cleaning. Dishwasher safe.
