“Suitable for eating sushi or defending the galaxy, the Luke Skywalker blue and Darth Vader red lightsaber chopsticks measure 9" long and its blades are cast in translucent material. The smaller 'children's sized' Yoda green lightsaber chopsticks measure approximately 7" long.” (link) Each set of Chop Sabers also include a translucent Star Wars logo chopstick rest.
The Chop Sabers will be available for purchase at SDCC next week, but after that there is no word on when these Chop Sabers will go on sale to the general public or their actual price. Hopefully they aren’t too expensive as they would make a great gift for that special sushi eating Star Wars fan in your life.
