Our super strength magnetic acupoint patch contains non-woven fabric + magnet. It allows you to target pain points in any part of the body with powerful magnetic therapy. Its use is simple: place the magnet on top of the gyro cast and place it over any pain points on the body. These healing magnets do not lose strength over time and can be reused on new replacement castings. And constant stimulation can be applied to pressure points for maximum cushioning.
