Thank you for viewing. This is a donabe (earthenware pot) for 1-2 people. I used it once and then stored it away, but the underside has become stained and the stain won't come off. There are no problems with its use, but please consider this before purchasing. The size is approximately 18cm in inner diameter and about 7cm deep. I also have other cooking utensils for sale, such as donabe, grill pans, and warming plates, so please take a look.
