This is one of my joys, meticulously taking apart old bike chain and giving it new life. These bracelets are made to last a lifetime. This one is made of stainless steel, copper, and bicycle chain. Please convo me your wrist measurement. This is a tough, beautiful, industrial chain that is my original configuration. It is likely you will never see anything like it on anyone else. It looks badass on a man or a woman, but so little jewelry is made that actually Does work for a manly man type guy that I figured I'd point it out.
