It's small, so it's easy to wash. I think it's suitable for about two people if you're not a big eater. I'm not sure where I bought it, but I think it was at Atre in Ebisu. The instruction manual says "Koyo Toki Co., Ltd." Please check the condition in the images, as I've taken detailed photos. Note: Recently, I tried using it before listing it, and I failed to cook rice, and the bottom got burnt. Therefore, the photos from the 14th image onwards show the current condition, and it seems the burn marks can't be removed. ~The following is from the website~ IH Bake Donabe (earthenware pot) size 7, 1 piece (Includes stainless steel IH plate and ceramic plate) Size (cm) Material *Actual size.
