This cup features a bite-proof Flip-it™ straw engineered to be durable and easy to use for your active child. The hard straw conveniently flips back to a closed position ensuring a leak-resistant seal. When ready to use the cup, simply flip the straw forward and sip from the bite-proof straw. The bite-proof straw features a Vari-Flo™ valve system made of silicone and engineered to help protect against spills or leaks. Liquids pass through spout only when your child sips.
