This was a gift, so the kiln is unknown. It can be used for things like pickled plums, pickled shallots, seasonings, and pickles, or even as an accessory container. Please understand that this item has been stored at home, and I would like to sell it to someone who can accept that. Thank you. Please check the final image for the size.
