These beautiful chopsticks are of natural Persimmon wood with a beeswax finish. After use, wash with water and a soft cloth. Because of the natural wood finish we do not recommend placing it in direct heat or very hot water. Oriental persimmon is native to China and has since spread to Japan and Korea. The chopsticks have a base of Japanese Persimmon (Diospyros kaki), harvested in China. They have a natural beeswax protective finish. These chopsticks are a little over 9 inches in length. Made in Japan.
