The NUK Action Cup toddler cup with straw is designed for kids on the move. Featuring a soft, flexible straw that disappears with a twist, it’s gentle on your child’s gums and easy to keep clean. It’s also 100% leak-proof thanks to an integrated valve that stops liquid from flowing when sucking stops. This NUK toddler cup is made from tough, high-quality BPA-free plastic that’s dishwasher-safe and easy to disassemble and clean. The tapered shape of the baby straw cup also makes it easy for small children to grasp. NUK has cups for every age: the NUK Trainer Cup for 6+ months, the NUK Magic Cup for 8+ months and the NUK Action Cup for 12+ months.
