Mystim Barry Bite Bipolar Contact Clamps with Gold Contacts. These bi-polar electro-conductive body clamps create a tingly, lustful pleasure at nipples, lips and various other body regions. Thanks to the fact that every clamp is bi-polar always only the tissue in between of the two halfs of the clamp is being stimulated. This means that you can stimulate both nipples at the same time, without any danger of leading electricity through the heart. Moreover the gold contacts of Barry Bite enable an especially intense and continuous stimulation. Length: approx. 160 cm. Material: gold-plated contacts. You will require an e-stim device - like the Mystim Tension Lover (MY46000), or the Mystim Pure Vibes (MY46010) - to activate the poles.
