Take them out of the case, and presto-change-o--snap Parts A (wood chopstick) into Parts B (stainless steel) and voila! you have your very own set of handsome chopsticks. Nerdy but in a good way! They come in a 5" long plastic case with a pocket clip. So it will slide into a pocket protector, or a pencil case, or purse. We come from a family that carries its preferred brand of soy sauce around, so this is right up our alley. It's kind of surprising how handy these come in.
