The NUK Trainer Cup makes the transition from bottle to cup easier. It features a soft spout that protects the gums and is easy to suck. The ergonomic handles allow little hands to grip and hold them. In addition, the air valve ensures uninterrupted feeding and the leak-proof design reduces stain cleaning. This sippy cup is also dishwasher safe, easy to disassemble, and made of durable, BPA-free plastic. NUK offers cups for all ages: the NUK Trainer Cup for +6 months, the NUK Magic Cup for +8 months, and the NUK Action Cup for +12 months.
