This is a Yeguangbei, a craft product from Gansu Province, China. Height: approximately 8cm, Diameter: approximately 5.2cm According to the translated instructions, it is made by cutting nephrite jade (jasper). This item was found while cleaning out my parents' house, and its history of acquisition is unknown. I believe it is probably unused, but as the box has some damage and dirt, and there is some dirt that appears to have accumulated during storage, I am listing it as "near new." Please be aware that this item has been stored at home for a long time. Please check the images before purchasing.
