This is something my grandfather made about 40 years ago, possibly a teacup. It has a mark that looks like the mitsugashiwa (three-tiered diamond) family crest. I think he probably made it for fun at the time. At first glance, it looks like a teacup, but it has three small feet. Please refer to the ruler in the image for the size. I am selling this because a considerable number of ceramic items were stored at home. It is unused, but please understand that it has been stored at home for a long time.
