Inner Lip Plate and Suction Lip Plate are designed to encourage independent eating. Ideal for one-handed dining, special lip prevents spills by letting food be pushed to the side of the plate, then scooped up with a fork or spoon. Both plates have a depth of 1/2" (13mm) and a diameter of 9" (23cm). The Inner Lip Plate is institutional dishwasher safe and may be microwaved or autoclaved. The Suction Lip Plate secures to the table using suction feet, is household dishwasher safe and should not be microwaved. Replacement suction cups sold separately.
