All earrings are made out of Polymer clay and are handmade with care. These love letter hoop earrings are made with hypoallergenic silver hoops for comfortable wear. They are lightweight and great for any occasion. Since each pair is handmade, there may be slight imperfections but I try to make each pair as identical as possible. Handle Polymer clay earrings with delicacy and care. Make sure to store in a safe dry place for a long life.
