When older tots are ready to graduate to the larger sipper, the 9 oz. Tot transitions straw cup is a great option. It features an almond-shaped straw that conforms to baby's mouth for less mess. The unique straw valve opens as soon as a tot's lips touch for easy drinking. Plus, the hinged cap closes to create a leak-resistant seal and protect the spout when not in use. The cap and straw are removable for easy, thorough cleaning. Pack of two.
