E-Stim Emporium
Mini Bipolar Conductive Rubber Nipple Clamps
These small bipolar electrodes have conductive rubber contact surfaces and are ideal for smaller nipples or even for use on the clitoris or labia.
They are very intense and sold in a pack of two. When clamped in place, the white ABS body and spring create a nice squeeze, and then your e-stim control box can get to work. Start low and build up slowly.
Although they were primarily designed for nipple play, they can be used elsewhere. Remember, if using them for nipple play, only use a control box with isolated channels and one channel per nipple. You could always opt for more than one control box, but the rule of one channel per nipple still stands. Don't run a current across or through the chest area.
