The EFX Nylon Corded Necklace features holographic technology that contains algorithms and frequencies that interact positively with this energy field in both humans and animals at the cellular level. When placed near the body, especially at key energy centers such as the hands and feet, EFX will harmonize with the body’s naturally occurring bioelectric frequencies. EFX effectively tunes the body, immediately unleashing its full potential for function and performance. Made from nylon cord and contains three holographic technology dots. The three holographic pods are re-positionable along the cord.
