These highly conductive electro-mesh gloves are made of woven silver fibers. The woven silver fibers actually conduct the current throughout the whole glove. Gloves are used primarily with all Perfector programs except for the Deep Cleansing and Iontophoreses programs. These gloves can be also used with the Arasys on the 1000 or 600 frequencies in cases where double chin and excessive fat in the neck area in the major concern.  They can also be used with the Ion Magnum at 100 Frequency, 9 pulse and 1-2 volts for cases where double chin and excessive fat in the neck area is a concern.  For higher voltage for both the Ion Magnum and the Arasys, you need to cover the clients neck with a wet towel and work with the gloves over the towel.  Conditions such as carpal tunnel syndrome, diabetic foot neuropathy, arthritis, poor circulation, tennis elbow, tendonitis, etc., may find greater relief from using these gloves. Stretch. One size fits all. Hand washable. Spray alcohol on the entire surface of the gloves after using with each client.
