Excavated in the capital city of Gaeseong, these bronze and celadon stamps were presumed to have been used by government officials. Their handles are in shapes of animals such as a lion, monkey, fish, or bird. The celadon stamps appear to have been modelled after the bronze stamps. Most of the bronze stamps had a hole, which suggests that these stamps were carried on a string attached through the hole. The base of each stamp is inscribed with letters along with popular patterns of the time or a symbol of authority.
