Good Chopsticks / product design

Good Chopsticks

In China, Chopsticks are used in pairs, when people have meals they usually count 10 chopsticks to make them into 5 pairs of chopsticks, when more people have meals, it will be more difficult to count. But it will be more convenient if chopsticks can be put in pairs when people grab it.
This is a pair of special chopsticks, a few changes were made on one side of them (the side without touching the food) in order to keep two pieces of chopsticks tightly holded when they are not used. Move down one piece of chopstick, compress the spring in another piece and then they can be easily separated. More details would be found from the picture.
