Just slide aside and drink! Help your little one drink independently with this Mepal Mio Straw Cup decorated with the sailboats and seagulls of Sailors Bay. After a few attempts your baby will quickly master drinking from a straw. And don’t worry, when it tips over it will not spill. It’s the perfect cup to bring along when you’re out and about. The slide closing is leak proof and keeps the straw clean. Simply slide open to reveal the straw as soon as your little one needs a sip of water.
