The Kira Hair Magnet Set are a set of 20 hair magnets with 5 different sizes, handmade in New York of gem-cut Czech crystals on durable silver toned magnetic hair clips They are designed to stay firmly in place, once other pins have the hairstyle securely fastened. We recommend treating each magnet as you would a piece of jewelry, and storing in the dust bag when not in use. Ensure to keep each magnet jewel set separate to avoid all magnets sticking together. Avoid contact with water, perfume, and other chemicals, including hairspray, which should be used before placement in the hair.
