Black Heavy Gauge Thick BCR Ring - Screw On Ball
Heavy gauge ball closure ring.
This ring is surgical steel, and is available in 5mm, 6mm and 8mm thickness.
The screw on ball means these can be opened by hand.
The bar length is the internal diameter of the ring. You do not measure the outside as this is not considered the wearable area.
Please note these are VERY heavy as they're solid steel.
