Steel Concave Back Taper (2 Inches Long)
Made of 410 ASTM implant grade stainless steel. All sizes have a concave back, are about 2" long, and are polished to a mirror finish.
The concave ends are slightly larger to allow jewelry to fit for an easy transition during stretching.
Below are the measurements of the concave ends for each gauge:
Jewelry is measured through a gauge system (see chart below). The higher the gauge number the smaller the wire is. A standard "earring" is usually 20 gauge. Jewelry gauges/sizes can vary between manufacturers. There is no universal regulation on companies to make a standard size in body jewelry. A big part of this is that some jewelry is made overseas and measured in millimeters. And in the USA jewelry is measured in inches/gauges. So many times jewelry can be anywhere from .5mm to 1mm different.
