A smart idea for travel. The cup has a lid that holds when opened, and the contents are protected from spillage by flexible slats that let your child's hands in but don't let the snack out. The cup is transparent so that it can be refilled in time. There is a handy child-sized tab on the side to attach the cup to a stroller or bag. 0% BPA, 0% PVC, phthalate free. Capacity: 222 ml Diameter: 10 cm
