Akagawa Kimono Seisakusho Silkware Oyako Nabe (Parent-Child Pan) This is a brand new, unused item. Oyako Nabe size: Outer diameter 16.5cm x depth 3cm. It can be used with induction cookers, and the Silkware processing makes it difficult for food to stick. I only opened it to take photos. Please purchase only if you understand that it has been stored at home. It will be shipped in a recycled box. Thank you.
