This appears to be an old Imari soba choko (small bowl for soba noodles) with a pattern of indigo butterflies and plants, but it's not entirely clear. Soba choko can be used not only for soba dipping sauce, but also as small bowls, dessert cups, and for various other purposes. They can also be displayed as interior decorations. Please check the photos for any cracks or chips. It has been cleaned, but please take a look at the photos and purchase it only if you are satisfied. It may be difficult to convey everything in the photos, so please understand. Thank you for looking at this item from among many others.
