Thank you for viewing. This item is new and unused, but it has been stored in a warehouse for a long time, so there is some dirt on the box and the product itself. I think the dirt can be easily removed by washing. Thank you for your consideration. It is compatible with direct fire, oven, and microwave, and can also be used for dry firing. It can be used as a shallow pot or as a ceramic plate. The material is ceramic (Iga-yaki coarse clay). The product size is approximately 25cm in diameter, 5cm in height, and weighs 1.4kg.
