This is a top-shaped cup with a sharp bottom. It is presumed that this type of cup with an inlaid design was unique to Goryeo. Scroll designs can be seen on the middle of the body, with materials inlaid into the blanks spaces. The characters “jung” (中) and “ok” (玉) are inscribed in black while “baek” (白) and “bae” (盃) are inscribed in white in double circles.
