We've plated these 1 3/8" long pieces of vintage flat brass chain in glossy black gunmetal. They feature hexagons, our favorite shape at the moment. The chain lengths move and bend in a wonderful slithery way, like the segmented exoskeleton of a bug, or a tank's treads. Posts are surgical steel and earring backs are 14K gold-plated brass. Earrings come attached to cardstock printed with the "Erica Weiner Jewelry" logo.
