If they hadn’t told us, we never would’ve guessed these awesome-looking bracelets were made from bass guitar string. Each bracelet is 9″ and rigid, though they can be bent to comfortable fit pretty much any wrist. Unfortunately, slapping this bass [string] won’t make a peep.

Check it out at CoolMaterial’s Shop (16$) or at Amazon (15$). Oh, and in case you were wondering, a guitar string version exists.
