It’s a powerful tool that reduces EMFs emitted by your phone. It’s made of many layers including a layer of 24k gold, 32 mineral layers, germanium, far infrared, and an absorbing layer that lies just above the adhesive patch. Together, these layers create a negative ion field that neutralizes and deflects the positive ions in EMF fields. Simply peel the sticker from its backing and paste it to the back of your phone, near the antenna (to the right, under the rear camera). The patch reduces radiation up to 90%, but will not interfere with your reception or interrupt your use. Just paste it and forget about it… It’s that simple!
