This is a pen modeled after the "Jadeite Cabbage," one of the most beloved works of art at the National Palace Museum. The "Jadeite Cabbage" is a work of art carved from jadeite into the shape of a Chinese cabbage, with a grasshopper realistically depicted on the leaves. The whiteness of the cabbage represents purity, and the grasshopper and locust on the leaves symbolize fertility. It is said to have been made as a dowry item, imbued with prayers for virtue and happiness. This souvenir can be purchased at the National Palace Museum shop, etc. There are some scratches on the case, but it is unopened.
