These items have been stored long-term in a storehouse. They are for someone who doesn't mind minor imperfections. I washed them once. After washing, I feel like there's a smell of earth. I'll check again after they dry completely or after some time passes to see if it disappears. I didn't notice it before washing. These are five lovely single-serving earthenware pots with plum blossom designs. I've already disposed of the box.
