The NoPull Piercing Disc was designed specifically for oral piercings, and wearers of Labret Studs but helps healing with any new piercing. The 7mm medical grade silicone disc lies between the inside of the piercing and the flat back of the jewelry. The NoPull Piercing Disc is a comfortable barrier, which keeps the jewelry backing from causing irritation, additional swelling, or becoming imbedded in the piercing. Piercings heal safely, more quickly, without discomfort, and without the anxiety! This is not an o-ring. The Disc cannot fall off, but is easily removed by the wearer, when they feel the piercing is healed.
