"Our Single Flare Clear retainers have a flat flare on one side and come with an o-ring to keep the jewelry in place. We suggest changing o-rings every 1-4 months. Most commonly used in labret, cartilage, & lobe 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."
