Heavy Gauge Hole Punch BCR Ring
Heavy gauge ball closure ring.
This ring is surgical steel, and is available in 2mm, 2.5mm, 3mm and 4mm thicknesses. All the thicknesses have a 12mm internal diameter.
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, you will need ring opening pliers to fit these as they won't open by hand.
