PowerFX bands are designed to maximize performance and improve overall wellness. PowerFX wristbands are made of 100% medical grade silicone, treated with negative ions. Each band features two exclusive PowerFX Hologram discs, embedded with proprietary holographic technology. We are the original developers of the PowerFX technology and design and manufacture our own bands. Each holographic disc stores a large amount of readily available information, carefully formulated, to provide the body with the resources it needs for harmony and balance.
