To use these earrings, simply open the earring backs and slide the studs through your earlobes, then close the backs securely. When wearing them, avoid contact with harsh chemicals like perfumes and cleaning agents, as they can damage the 18K gold - plating. After each use, gently wipe them with a soft, dry cloth to keep them shiny. Store them in a jewelry box or a small pouch to prevent scratches and tangles.
