Reevaria - Pure Copper Magnetic Heavyweight Cuff 'Follow Your Heart' Bracelet for Men, with 8 Magnets 3500 Gauss- Recovery and Pain Relief - Arthritis, Golf and Other Sports, Carpal Tunnel

The inside material should be made of something other than copper because who wants to walk around with a green ring around their wrists? I wore it for 4 days and chunked it in the trash. Not worth the money and very disappointing!

very good
