This pad is our own design and manufacture, you won't find it anywhere else. It's a bipolar design for above the waist safety. The hole in the middle is meant for nipple placement, and the rest of the wrap folds around the breast itself to guide the current directly through the areola and nipple.
The smaller sizes have a more intense/tingly feeling where the larger sizes are more mild/massage type of sensation.
Sizing note: 25mm=1 inch. That makes these roughly 1.5 x 2 in with 1/3 in hole in the center.
**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!
