The Peekaboo straw cup by Done by Der is the perfect size for small hands. Wally peeks out from the fun cup and sprays water droplets onto the straw. A practical lid keeps the straw in place and the liquid inside, making it easier for the little ones to use the cup. The sweet Wally cups are made from food-approved silicone that makes them unbreakable and easy for baby to hold. Approved for use in dishwasher, microwave, oven and freezer. A convenient brush for easy cleaning of the straws is included.
