 - Titanium became one of the most favourite materials of professional piercers. It's, at the same time, very strong and very light; it is able to resist to body acids and fluids. Thanks to its properties, this material is able to avoid all types of tissue and bone allergies. For these reasons it is widely used for permanent surgical transplants. PER4 only uses titanium grade 2 and 23 (Ti6AL 4V Eli) and suggests its use to perforate. We fulfil the European Nickel Directive.
 - P.T.F.E. (polytetrafluorethylen) benefits:
- It can be sterilized by autoclave at 160 degrees.
- It's totally flexible, biocompatible and transparent.
- It is anti - allergic.
- It's easy to cut following one’s need.
- This material is highly recommended to perforate.
 - P.M.F.K. (polymeric medical flexible plastic) benefits:
- It can be sterilized by autoclave at 120 degrees for 20 minutes or at 134 degrees for 5 minutes.
- It's less flexible than the P.T.F.E., so it allows creating circular barbells or bananas.
- It's available in different colours.The P.M.F.K. is totally biocompatible because the colour is dissolved
directly in the polymeric.
- It's easy to cut following one’s need.
 - PER-4 uses 316LVM - ASTM F138-97 surgical steel. the same that has been used in surgical implantation for more than 20 years.
The 316LVM steel is melted in an oxygen free atmosphere. thanks to it. the quantity of carbon is highly reduced and. at the same time. the material turns out to be free of toxic elements that could contaminate the jewels surface.
 - All our Black & Gold Items are made from 316L Surgical Steel with Black PVD (Physical Vapour Deposition) coating.
 - Our horn and wood products are unique and are handmade. No items esquals 100% another one.
Our materials are real natural products and fulfill the European Import Directives. Per-4 does not recommend these product for initial piercing.

We only work with stone setting and with first choice silver, the “925” branded one.

 - PER4 offers you a wide range of acrylic articles that thanks to their colours, designs, fluorescent properties and competitive prices have been very warmly welcomed in the market.
Anyway, we suggest you to be careful in using the UV products, because they can’t be sterilized and they can’t be used for perforation. Their biocompatibility has not been certified yet. The banana bar, the part of the piercing that enters in direct contact with the skin, can be made either of 316L surgical steel or Titanium.
