摘要:
Attractive, inexpensive, sanitary and effective chopsticks are formed of elongated, hollow tubular elements formed of relatively rigid, non-toxic plastic having closed upper and lower ends. Corrugated portions are provided near the lower ends which extend substantially entirely about the hollow tube so as to provide an improved gripping surface.
