**I do not have the box or original packaging, but there have never been worn*** The Zinnia Earring is a post earring with a surgical-steel post, which is safe for sensitive skin. Our earrings are nickel-free. This earring is made by hand in New York from mother of pearl, pearl, and gold-tone plated brass. We recommend storing earrings in their dust bag while not in use, and avoiding contact with water, perfume, hairspray, and other chemicals.
