This bottle is carved in the form of a Japanese inro, a medicine container with multiple 'cases', usually made in lacquer, attached to a cover by cords hanging from the belt. Two enamelled metal inro with Yongzheng reign marks in the National Palace Museum prove that the form was known to the Chinese Court in the 18th Century.
