Eobo, the official seal of the king

Eobo is produced for ceremonial purposes at the time of the coronation ceremony of the king and queen, in praise of the virtuous deeds and/or to convey the significance of integrated re-evaluation of the governance by the king. Such Eobo is then enshrined with the ancestral tablet of the king or queen in royal ancestral shrine after their death to symbolize the continuity of the dynasty and legitimacy of the royal family. In addition, if it is used to symbolize the nation and succeeding of the throne, and actually used in state affairs including affixing of foreign diplomatic documents, it was specifically referred to as the Guksae (state seal). Accordingly, process of production, types and usages of Eobo are explained below.
