This ornate celadon brush holder with an exquisite openwork vine design and twin dragon heads demonstrates exceptional sculptural expertise. Each of the dragon heads is carved in meticulous detail with a distinctive mane, frills, fangs, and scales, indicating that this item was made for the royal family or a very high-ranking aristocrat. It is considered an important artifact simply because this type of brush holder is very rare, but more than that, it is exceptional in its own right for the aesthetic form and glaze color that make it a true masterpiece of Goryeo celadon.
