Every set of earrings are handmade with polymer clay. Earrings are so lightweight you will forget you have them on! Earring backs & posts are nickel free. Since all items are made by hand, slight variations, imperfections & difference will occur. I always strive to get the truest colors in my pictures so you know what you are getting. CARE: Store items in a clean & dry area. Do not wear in the water. Can clean with a baby wipe. Earrings are delicate so store carefully so they will not bend or scratch.
