Ultra Violet (UV) Ball Closure Rings react to ultraviolet light and glow in many different available colours.
Ball Closure Rings are used in body piercings and can be made of different materials, such as Surgical Steel, Blackline, Zircon Gold, Titanium, Gold, Silver and Acrylic.
The ball of a BCR is held in place by the tension of the ring; there is a dimple on either side of the ball for the ring to clip into.
To remove the ball you must push it out of the ring; it does not unscrew. To fit the ball back in, line one dimple on the ball up with one side of the ring. Hold the ring firmly and push so that the other dimple clips into place. If the ring is too tight to clip your ball into, Ring Opening Pliers can be used to make this process easier.
