The craft of najeonchilgi refers to lacquerware inlaid with nacre (mother-of-pearl), including such items as furniture and accessories.

The surface of the lacquerware is with decorative patterns made by inlaying very thin pieces of nacre (processed from iridescent shells, such as abalone).

Tongyeong, which harvests many abalones, is famous for najeon chilgi nacre-inlaid lacquerware.

This two-tiered chest of lacquer inlaid with mother-of-pearl depicts landscape designs and hexagonal flwer patterns (龜甲花文).

Here, the inlay technique involves slicing the nacre into thin thread-like strips

and stretching them with the tip of a knife before cutting them off and attaching them to the object.
