POWER BALANCE necklaces contain two Mylar Hologram&＃39;s which are embedded with frequencies that react with your body&＃39;s electro-magnetics field. When the static POWER BALANCE Hologram comes in contact with your body&＃39;s energy field, it begins to resonate in accordance with each individual&＃39;s biological energy system, creating a harmonic loop that optimizes your energy field, maintains maximum energy flow while it clears the pathways so the electro-chemical exchange functions like the well-tuned generator it was designed to be, resulting in immediate improved balance, increased core strength, greater flexibility, increased range of motion and overall well being.
