New, unused, and stored in a bag for a long time. This is a product of Daiki Mengyo Co., Ltd., made in Japan. The bag is also a bit dirty, but I took it out for the photos, and the item itself is clean. Size: Diameter: Approximately 15cm Depth: Approximately 20cm (pointed at the end) There is no indication of how many people it's for, but I think it's suitable for about 10 people. I would appreciate it if buyers understand that this is an old item.
