This item has been stored at home for a long time and was used at home. There are many stains and scratches. I washed it with dish soap before listing it, but they didn't come off. It shows signs of use. Diameter 24cm, height 10cm, gas stove only. No box or instruction manual. The lid has an "M" shape, a King mark, and the words "Mizu Nashi" (meaning "no water" or "waterless"). Please understand this before purchasing.
