The Oxo Tot Stick & Stay Suction Bowl features a secure suction base that sticks firmly to surfaces until mealtime is over. The parent-friendly design makes these plates and bowls easy for grown-ups to remove, but tricky for little ones, to prevent slipping, tipping or tossing. The side walls are designed to help tots with scooping to help promote self-feeding. These dishwasher safe bowls and plates quickly twist apart for thorough cleaning.
