Earrings are made with polymer clay and resin with a nickel free, stainless steel post. The organic circles may vary in size and marble design. These earrings are handmade and very lightweight. They are perfect for everyday wear. CARE & CLEANING: Please note that polymer clay makes durable and slightly flexible earrings, however care should be given so as not bend or break earrings. Store in a cool, dry place. If needed, please gently clean earrings with a damp cloth. Always ensure that they are kept away from perfumes, nail polish and cleaning agents (especially those with acetone and alcohol as they may affect the surface texture of the earrings). Earring components may tarnish when exposed to humidity, therefore each order comes with a polishing cloth.
