Stud earrings made from lightweight polymer clay, and measuring approximately .05-0.6 inches. Posts are stainless steel. They are tarnish resistant & a great option for sensitive ears. While we make every effort to photograph jewelry true to color, color may vary slightly due to your screen settings. Due to the handmade nature of this item, slight imperfections may occur. We suggest you do not expose earrings to harsh chemicals such as perfume, makeup or hair products. Store earrings in a soft pouch or jewelry box when not wearing them, and remove them before showering, swimming or sleeping as exposure to water or bending could cause damage.
