It is a white porcelain tokkuri from the Joseon Dynasty. Households of the Joseon Dynasty used such tokkuri to make soap from waste oil.
With use, the porcelain frayed and curled up again, and the worm-eaten mouth and the oil-stained scenery engraved on the white porcelain are traces of the simple life of the time. The dignified appearance with deep taste is one and only.
It smells a little oily. There is no water leakage, but if you use it as a flower vase, please use it after preparing a bamboo cylinder dropper.
