These are real African-made copper bracelets from the Congo, Senegal or South Africa. Generally, the bracelets are about 7.5" on the curve, and the widest part is about 0.5". All of the copper bracelets weigh approximately 0.2 to 0.7 oz., and, except for the Malachite or Cow Horn bangles, are bendable/adjustable.
These flat top and wire bracelets come in several variations. Please see group photo for examples.
