It is the original intention of the birth of OOAK and a deeper interpretation of "one of a kind". Jiege is a typographical term derived from Chinese calligraphy. It can be freely retracted and released, just like OOAK's pursuit of the "design feeling of enjoying the benefits": it is not limited to materials or processes, and it is more human-oriented design to explore the artistic feeling that can withstand the precipitation of the times. It uses modern design of enjoying the benefits and jewelry technology to present modern art jewelry that is integrated into daily life.
