There are four pieces in this set. They are a pen holder, a pen holder, an ink pad, a pen wash, and the size of the utensils. The main decorations are the same. They are all painted with enamel and painted golden clouds and dragons. The windmill is vigorous and powerful, with moiré in the middle, adding a sense of movement to the picture. The bottom of the vessel is signed: "Qianlong Years".
