Various Zippos custom decorated in Korea, using traditional artwork called «Nageon Chilgi», with black lacquer and mother-of-pearl inlays as decoration including personal initials/name. «Najeon» means mother-of-pearl and «Chilgi» refers to lacquerware. The Abalone shell is first carved, then applied to the case. Layers of lacquer are then applied. The artist would then hand polish the entire surface revealing the Abalone shell underneath.
