For those with sensitive ears or metal sensitivities, I now have hypo-allergenic ear wires available! I make these ear wires by hand using anodized niobium wire, in the same sizes and styles as my bronze ear wires. To purchase earrings with hypo-allergenic ear wires, purchase both the earring listing and the listing for the ear wires. I will replace the bronze ear wires with niobium wires in the same style, and in the best color match for the metal in the earring design.
