The Philips avent my bendy straw cup 10oz is the ideal choice for the growing active toddler. This dentist recommended cup was developed alongside experts in order to make it our best straw cup possible and one that allows for healthy oral development. The cup's contoured shape and anti-slip texture grips make it easy for little hands to hold the cup. The 10oz cup is the perfect size to keep your child hydrated throughout the day and through active times. With this straw cup your child will be able to drink 'til the very last drop thanks to the Philips avent unique bent-straw - the lower part of the straw is elongated and bends forward ensuring the straw easily reaches the cup's contents and allows the development of a natural drinking position. The cup has an integrated anti-leak valve to prevent spills (even when the cup is open!) and the flip-top protects the straw and prevents leakage while on-the-go.
