Candy Co. Bangles are fully adjustable and will fit most wrist sizes. We designed them to be delicate, lightweight, comfortable and durable, so you can wear them daily, to work or play. Our bracelets are made of hypoallergenic, lead free, 14 gauge 1100 food safe aluminum metal. CARE To clean, wipe with soft cloth. Avoid frequent contact with strong chemicals, such as detergent, bleach, perfume, etc. Store in a jewelry box or soft cloth We use aluminum, stainless steel, copper, and brass (nu gold). Aluminum and stainless steel give the look of sterling silver without the cost. Pure aluminum does not tarnish and has a much lower rate of skin reaction than sterling silver. Copper and Brass (Nu Gold) will patina over time and cause it to create a very unique aged antique look which is simply gorgeous. However you can polish both metals back to their original shine with a polish cloth.
