In the east, chopstick serve a very important dining culture, every family has several pairs of chopsticks, but they are not the same kind.
The difference may be colors or makings.
Therefore, people have to pay attention on picking the same kind of chopsticks to make it a pair that cause inconvenient.
Inspired by nunchakus in chinese martial arts, two chopsticks are chain together that make it a pair. Not only we can hang to dry after washed, but also the chopsticks will not fall out when putting by the side of bowls.
