This is a sake cup purchased at an antique market. It's a sake cup with a thin rim. The inside features Okusan (a symbol of good fortune). What's a little unusual is that the nose and mouth are made of characters. The name "Yamaguchi" is hidden within. It's a rare item. It's likely a commemorative sake cup, perhaps for longevity or a similar occasion. There don't seem to be any noticeable large scratches or chips. Please check the images carefully.
