This is a Wide Oven Cocotte from Asahi Keikinzoku Kogyo. Diameter: Approximately 13cm (body) Height: Approximately 9.5cm (body + lid) Capacity: Approximately 500ml Cannot be used with IH cooktops. It was stored in its original box, wrapped in a plastic bag. The green one is spotless, but the yellow one has some stains on the bottom. I washed it thoroughly, but they wouldn't come off. There are no scratches.
