mid-century retro square cream/sugar

1950's heavy grey melmac cream and sugar, great mod square shape! These are about 3 1/2" x 3 1/2" x 2 1/2" deep. It's marked Arrowhead, although this is the Brookpark design (so marked on other pieces we have in the same pattern). Condition is clean and nice, doesn't look as though this was ever used.
