How do you get famous musicians to donate their cast-offs? Promise them the profits will benefit a good cause. I've seen it before with watches made from guitar straps and now Relix magazine and Azu Studio have created a line of guitar string bracelets made from strings from famous musicians. Each one is guaranteed to be from a celebrity. The prices vary according to the fame of the musician: Ben Lee will only run you $75 while Ben Harper will cost you $150. The most expensive bracelets come strings from Pete Townshend of The Who and Jack Black/Kyle Gass of Tenacious D which cost $300 each. Men's and women's sizes are available.
