Nickel-free ear posts and components. The earrings are made of polymer clay, they are lightweight on the ear. All earrings are designed and made in my South Florida home. Due to the handmade nature of each piece, slight variations in color, shape, etc. may occur compared to the picture. Earring price INCLUDES tracked and insured shipping through USPS. CLAY CARE: Polymer clay is durable and slightly flexible, but at the same time it is a delicate piece and must be handled with care. May break if dropped or handled improperly. When not in use, store them safely in a cool, dry place. Use damp cloth to wipe away any residue or dust. Dip a cotton swab or Q-tip in rubbing alcohol to wipe away any stains.
