These are bipolar pads safe for above the waist stimulation with a few safety exceptions. They send the stimulation currents within the circle rather than across the chest surface.  Also very pleasant when placed around or under the scrotum and the genital areas. 

Sold as single pads, not sets. 

Sizing note: 25mm=1 inch. That makes these roughly 4.6 x 6.5 inches. 

**All pads can be purchased as single sheets or in packs of 3, 5 or 10 at reduced pricing. Larger quantities also available, just ask!
