melamine bowl set (Derwood, MD)

Set of 3 dishwasher-safe melamine bowls (see photo); the small one is 7” diameter and 4½” high, the medium one is 9½” diameter and almost 6” high, and the large one is 11” diameter and 6½” tall. Clean and in very good condition (I’ve used them regularly until today, when I bought a new set), but the medium one is missing the rubber base (not really needed) and its lid has a little discoloration.
