Diameter approximately 6cm x 4cm. There is a maker's mark on the back, but I don't know the details. I couldn't find a wooden box (kyobako) or other related items. It has distinctive glaze like Kawachi ware. The silver decoration has discolored to black. Please bid only if you understand that this is an old item.
