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 (6.5 x 1.65)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.
