19th-century Seto sometsuke (underglaze blue) ware. I've never seen anything like it, and as it's just the right size for a sake cup, I decided to purchase it. There are some glaze skips. In addition, as it is an old item, there are scratches and stains commensurate with its age. Diameter: Approximately 7.4 x 7.7 cm Height: Approximately 6.4 cm Sizes are approximate. The actual item may differ slightly in color from the images. Please understand the description and images before purchasing.
