Hol is a small and long plate held in the hand when wearing the Jobok, and was intended for recording in case the orders or commands of the king were forgotten, but was institutionalized for ceremonial use during later times. According to 『Gyeongguk Daejeon』1485, 1st~4th ranks used ivory, and 5th~9th ranks used wooden Hol, and this system was maintained until the late Joseon Dynasty. This Hol is made of ivory, the middle part is slightly curved, and the lower part held by the hand is wrapped in blue silk.
