The BioFlex brand was originally developed by a professional body piercer from the UK to be marketed to the body piercing industry. BioFlex is made of medical grade plastic, which makes it perfectly suited to the body piercing jewelry industry - it's even used in some medical applications. BioFlex is hypo-allergenic, making it without question one of the best materials to use in a piercing due to its safety. The jewelry is extremely flexible and easy to insert and remove, making it perfect for both initial piercings and long-term piercings for active users - especially if the bright and vibrant colors that BioFlex can be fashioned into are desired! As of 2013, Salamander Jewelry has been the prime source for BioFlex body jewelry - we acquired the original manufacturer, making Bioflex a part of our official production line. We now produce BioFlex body jewelry in 11 different colors and with 8 crystal & Cubic Zirconia color profiles. All of the adornments are set into our jewelry with our unique glue-free method for added safety and durability. BioFlex complies with the below regulations for Medical Use: the European Council, European Pharmacopeia - 3rd Edition (1997) and Supplement 2001 Monograph 3.2.2 USA. The material has passed Class IV tests (for Bio-compatibility) of the United States Pharmacopeia XXIV and has also been approved by the U.S. Federal Drug Administration.
