These are rice bowls purchased from Belle Maison, which are still being sold. I bought two sets of two colors (a total of four bowls), but since my children are small, I haven't used them much. One is for my husband who is working alone, so I am selling the remaining three. The colors are: Gray: 2 bowls Beige: 1 bowl Specifications are as follows: ● Diameter: approx. 17cm, Height: approx. 9.4cm ● Full capacity: approx. 900ml ● Product weight: approx. 425g ● Main material: Porcelain ● Microwave safe ● Oven range not usable ● Dishwasher safe ● Made in Japan For more details, please search for "Belle Maison Oishiku Taberu Donburi 2-color set [Made in Japan]". Also, all bowls have been used only about twice and are in beautiful condition, but please refrain from purchasing if you are overly sensitive to minor imperfections.
