DESC: Moms, have no fear the Avent Magic Cup is here! Now your little ones can drink without you having to worry about messy spills and clean up. The trick is the patented non-spill, easy-sip, Magic valve found only in the Avent Magic Cup. While drinking, the valve flexes open to allow air in, which then allows a continuous flow of liquid out. That means less suction is required, making the Magic Cup easier for infants and toddlers to drink from. In fact, the Magic Cup is so easy to drink from you can introduce cup feeding months earlier than other non-spill cups. Unlike other non-spill cups, the Magic Cup even works with pulpy juices. When not in use, the Magic Valve closes so no messy spills appear.
