This is a Banko-yaki serving bowl. It's oval-shaped, approximately 23cm long at its longest point, and about 8cm deep. These measurements are approximate, taken by a non-professional. Please allow for some error. Although unused, it's listed as "like new" due to long-term storage. There may be some overlooked scratches. The box is quite dirty. The brand name and other details are based on my own research. There may be errors. If you require perfection, I recommend purchasing from a specialty store. Please refrain from purchasing if you have any concerns.
