Bioplast Gem Nosescrew and Nosebone Set
Each of these sets include a bioplast nosescrew stem and a bioplast nosebone stem, as well as a gem end that will fit either design.
The stems can be autoclaved, but the gem end cannot.
The gem measures 2.5mm.
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.
