AVOID CLEANING UP MESSY SPILLS AND LEAKS!Kids are animated and active, even while holding (and occasionally dropping) their drinks. The Nuby Easy Grip Soft Straw Sippy Cup is here to help parents stop worrying about spills and leaks! Each unisex 10 fl oz sippy cup is designed with a soft silicone straw that helps prevent drips and spills while being gentle on gums and emerging teeth. For extra security, the cup straw has a pressure-sensitive Touch-Flo valve that helps regulate fluid intake as children drink. When sipping stops, the valve closes for a leak-resistant cup. The ergonomic shape features grips to ensure a comfortable, secure grasp for small hands. Whether your little one is at home, in the car, or on the go, they can stay happy and hydrated without ever leaving behind their favorite cup!
