This listing is for ONE bangle. Create your own set by choosing your size and number of bangles at checkout. Each bangle is approximately 1/8” wide and is made from jeweler’s brass. They have been soldered into a complete circle, sanded, and polished to sparkle. The bangles slide over your hand onto your wrists. To measure, we suggest you touch your thumb to your pinkie, then measure the circumference of your knuckles in that position. We will use this measurement for the inner diameter of the bangle. Our jeweler's brass consists of 85% copper and 15% zinc. Our bronze is made of 85% copper and 15% tin. Our copper bangle is 99.9% pure. 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. In some, the copper in the alloys and the copper in the solid copper wire 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.
