The new Philips Avent cup is compatible with the Philips Avent Natural and Classic+ bottle range (excluding the glass bottle), and all other Philips Avent cup (excluding the Natural Drinking Cup). The angled spout is designed to help toddlers take their first sips easily without tilting their head back too much. Trainer handles help your toddler to hold the cup and drink independently. These handles are not only shaped for little hands to grab easily, they are also rubberized for a non-slip grip. This Philips Avent cup is made from BPA free material.No more mess! The new patent pending valve ensures that water comes out only when the child is drinking from the spout. Simply remove the valve and the sippy cup becomes a free-flow cup. Whether at home or on-the-go, the protective hygiene cap always keeps the spout clean.
