Create your own set by choosing your size and number of bangles at checkout. Each bangle is approximately 1/5” wide and is made from bronze or copper. Each bangle has been shaped and polished to sparkle. They are not connected, so they "clink" on your wrist. They are not adjustable since they are so thick. They will slide over your knucklels. To size, touch your thumb to your pinkie. Hold that position and wrap a tape measure around your knuckles. That circumference is your bangle size. Bronze is an alloy made of 85% copper and 15% tin. The copper is 99.99% pure. In some, the copper in both metals may turn the skin green. If this happens, we recommend coating the inside of the cuff with fingernail polish to create a barrier between the bangle and the skin. Reapply as needed. NOTE: Each bangle is in its natural state. It’s not coated with anything to prevent tarnish. Oils, lotions, moisture, etc. will accelerate the tarnish, so its recommended that you use a jewelry cloth for cleaning after wearing your bangle.
