Kids can operate on their own with easy grip handles & volume markings so you know how much baby is drinking. Dishwasher & sterilizer safe. Leak Proof & Spill Proof: Our unique two way valve ensures easy drinking with no leaks or spills, even when the cup is on its side! And the flip top lid clicks into place to keep the straw clean on the go.
