This piece has been created from recycled copper tubing, hand created and designed. Very heavy and sturdy piece, 1 1/4" wide, great for summer attire. One size fits most. Copper may turn your skin green if you perspire, do not worry this is a normal reaction due to the acidic content in your perspiration, actually copper is believed since ancient times to be beneficial to your body, but I will leave that research to you. It is best to store copper jewelry in an airtight zip lock bag to prolong it from tarnishing. If it tarnishes you can shine it back to its brilliant state with many easy to find rubbing compounds and even common household items.
