Thanks to the No-Spill spout the cup can fall over, it won't leak! The secret? In the spout there's a built-in valve that only lets fluid run when the child pressures it. The different textures on the spout protect the valve against pressure of teeth. This Vari-Flo -system allows your child to control the flow rate himself. The spout is easy to clean and assemble. The ergonomic shape of this fun Nby cup promotes natural drinking and a healthy oral development. This cup is suited for children from 6 months, on. It contains 240ml and is available with 4 fun color combinations.
