Warning: current must never flow through the heart. Do not use if you have a pacemaker, are pregnant, if you suffer from epilepsy, or on any broken or inflamed skin.<br /><br />No matter what size you are these Rubber Cock and Scrotal Loops from ElectraStim will hit the spot. The size adjuster keeps them in place and because they are made from super conductive rubber they will expand when you do! Use one ElectraLoop around your scrotum and one around the base of your cock. Adjust each loop to the required size using the sliding adjuster and add a lick of conductive gel to each loop at the point of skin contact. Connect one end of each loop to the cable and you are ready to go! Do not connect the cables to each end of the same loop, this will just short circuit the stimulation. Adjustable up to 2.75 inches. Made from skin safe conductive rubber with plastic sliders. Phthalate free. Latex free.<br /><br /> *Lubricants are a natural up-sell to electro stim toys as they are needed to completed the circuit between the toy and skin, and also help avoid skin irritation. Water based lubricants are recommended based on their high ability to conduct electricity. Silicone is a natural resistor and is not recommended.<br /><br />Please note: this item requires a powerbox to function.
