This Folsom electric anal plug is made from a durable plastic compound for long life. The two silver strips on the sides are electro conductive allowing the electricity to flow from one end of the plug to the other. With its special shape, this plug will fit nicely into the anus and can deliver a mild to strong stimulation depending on the power unit settings. With proper experience one can enjoy sensations only available through electrosex. You have a choice of three different anal plug sizes: Small: 4.5" of insertable length and 1.25" in width. Medium: 5" of insertable length and 1.5" in width. Large: 5.5" of insertable length and 1.5" in width. Compatibility: This product is a bipolar product so it's ready for immediate play with Folsom or Erostek equipment. However, a pins-to-banana adapter is necessary for use with our Rimba units. If you would like to use this product with our Digital Power Box (VF170), just use the snapper adapters to connect.
