Non-spill, easy-sip Philips AVENT Magic Valve found only in the Philips AVENT Magic Cup. While drinking, the valve flexes open for air to flow in, allowing a continuous flow of liquid out.
That means less suction is needed, making drinking from the Magic Cup easy for babies and toddlers.
So easy in fact, that you can introduce cup feeding, using the Magic Cup, months earlier than other non-spill cups.
