Many people believe that copper or brass bracelets have health benefits, including better circulation and relief from arthritis pains. In ancient times copper symbolised love and balance and has been used for centuries to heal and protect. Bracelets keep the body in a stable state which leads to better results in meditation and yoga practice. 
They also say hand crafted in Nepal.. so you can tell your friends these are made on the roof of the world.  Because the bracelet is metal it can be gentle bent to fit any wrist - so also effectively unisex.
