Notes on Professional Installation

The installation of a microchip implant should always be done by a professional. We are happy to send an installation guide or consult your piercer.

Do not install an implant under a grip area (e.g., no installation on the palm).
Do not install over or parallel to joints (flex implants are only "semi"-flexible)
