Thanks to the leak-proof no-spill straw and the retractable closure flap, the straw cup can fall over and nothing will leak!

The drinking straw has a built-in drinking valve, which only lets liquids through if your child puts pressure on it. This Vari-Flo system allows your child to determine the drinking flow themselves. The locking flap keeps the straw clean when not in use. The handles make the transition from the bottle to the drinking cup easier.
