Our Flat Flare Curves have a flat flare on one side and come with a silicone oring to keep the jewelry in place. We suggest changing orings every 1-4 months. Most commonly used in vertical labret & navel piercings. Jewelry of this size is very fragile. Caution must be taken when wearing small gauge glass. It can break when a force is exerted on it. DO NOT wear during athletic or other physical activity.
