I believe this is a refined rice bowl with an elegant blue pattern, a design that won't get old. I received it as a gift and have stored it at home for a long time, but since my family is small, I haven't used it. I'd like to offer it to those with large families or businesses that need it. However, each bowl has a slight black stain, like a material stain, on the inside. I don't think it will cause any problems for everyday use, but I don't recommend it for those seeking perfect condition or who are very particular. Also, there are markings on the case for storage. Please understand this before purchasing. Color: Blue Type: Rice bowl Material: Ceramic Size: Small (Diameter: ~17.9cm)
