The Vitalon pendant acts as an amplifier for the information that you choose to place inside it. It can be unscrewed and along with the ball of crystal (provided), you can add anything from homeopathic granules (like arnica) or even positive affirmations handwritten on paper. This heightens the vibrations and the affirmation or healing energy that can be transmitted to the subtle energy field that pervades the person or even a pet. The affirmation or medicine can be changed as needed.
