The wood is carved into different shapes that produce the negative form of hearts, clubs, diamonds and spades when the sticks are placed next to each other. An aluminium core is embedded inside the wood to compensate for the weakness created by the carving. A gap in one side of the square-shaped Kamiai chopsticks enables the two pieces to snap together when not in use. Magnets placed on the outside of the sticks hold them in place but stop them sticking together while eating.
