All earrings are made out of Polymer clay and are handmade with care. These Halloween stud earrings come in three shapes: an orange pumpkin, black bat, and white ghost. They are lightweight and great for any occasion. The gold earring posts are hypoallergenic making them comfortable for wear. 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.
