We have a vintage opalescent / iridescent figurine with two dogs. Stamped on the bottom in black with, "Japan."
They have hand-painted faces and uneven glaze coverage (top of the heads and nose of the right side dog). Not sure if this was intentional but it was made that way. They measure 1 5/8" tall, 2 1/2" wide and 7/8" deep. No issues. No nicks, chips, cracks, breaks or repairs
