This is our largest dildo in the Linear bi-polar range and has the ideal shape for that authentic feel! The linear design means that no matter how much or how little is inserted, you will feel the electro sensations coming from either side of the dildo. Size: 165mm Insertable length x 42mm diameter e or approximately, 6.5 inches by 1.65 inches. We take a piece of 6mm thick clear acrylic, bond it between two solid metal bars with aircraft strength adhesive, add 7 nitrile insulating o-rings, press a 2mm pin socket into each pole, then shape and polish our Rocket electro dildo to a fine finish. The result is spectacular. Exclusive ElectraStim Rocket Design Crafted from an engineered laminate of marine grade aluminium and acrylic 165mm penetration depth by 42mm diameter O-rings around the base form a good insulating grip and can be removed for effective cleaning 2mm pin socket compatible. You will need an ElectraStim erotic electro stimulator to use this item. If you are using a different power box and your cable does not have the 2mm pin connector you will need an adapter kit.
