noüka’s Silicone Straw Cup is the perfect transition cup between a sippy cup and open cup! When it's time to drink, simply twist the spill-proof tab on the lid and insert the silicone straw through the opening. Pop the tab back into place to store in the fridge or while on the move. The soft, silicone straw is safe for teething little ones, and once they're ready, just remove the cap so they can practice drinking from an open cup. Made from food-grade silicone, this straw cup is easy to clean, durable, and long-lasting.
