This is an ok-iro (hibachi) used for the tea ceremony, which I found at my parents' house. Power supply has been confirmed. I believe the small parts are for plugging the holes and for placing incense. Length: Approximately 39.7 cm Width: Approximately 39.7 cm Height: Approximately 20.5 cm There are no major scratches or stains, but it is a used item that has been stored at home for a long time, so thank you for your understanding.
