Cups measure 3.75 inches tall and 2.5 inches in diameter. They feature a band of gray, black and royal blue spirals/waves on a white cup. Cup is flared slightly on the top and bottom. Great mid-century design! Saucer is a rounded square, white, and is banded with black and gray. It measures 5.75 inches across. This is a lovely but hard to find pattern! MPN 2358  ss1
