This is a set of bowls and trays from the Zuitou brand. The bowls are a slightly larger size, and seem suitable for ozoni (New Year's soup) or light donburi (rice bowl dishes). Size: Bowl: Approx. Φ13cm Height: Approx. 8.2cm Tray: Approx. 16.4cm square Material: Bowl: Ceramic Tray: Plastic (Material is based on the seller's judgment as there is no indication) This item has been stored at the seller's parents' house for many years, unused and in new condition, but it was slightly dirty, so it has been washed. The original box has deteriorated, so it will be shipped in a different box. There are scratches on the tray, as shown in photos 8 and 9. If you do not need the tray, we can offer a slight discount, so please comment if you would like to discuss it. Please purchase with your understanding of the above. Thank you for looking.
