These are the UNIPOLAR option. This means two are required to create a sensation pathway.
These come in 2 sizes, small and large. Small is approximately the size of a wrist, Large is approximately the size of a female C or D cup breast. They have by far the strongest spring of any clamps we carry.
They also feature our new multi-connector: you can snap on to it, or put either a pin or banana through the hole and screw it down. No adapters ever needed, but works best/most secure with snaps. ***NOTE- these fit the larger 3.9mm snap!*** We have adapters here or purchase them together at a discount.
Male applications include a small one behind the corona and a large one behind the ballsack.
Females generally prefer two large ones on the breasts.
