Zougan-Zaiku is a form of marquetry in which a wood surface is finely carved and then inlaid with shells or wood. Shells are trimmed into various shapes before inlaying, while wood pieces are carefully molded before being carefully fitted into the base material to create a decorative surface. The completed surface is then often lacquered to enhance the colors and protect the wood. Chopsticks, tableware, and other types of Japanese goods are made using these methods.
