Stainless Steel Ball Stretcher with studs and spikes inside and outside, when the spikes are turned they screw into the centre in a vice like manner (for extra stimulation). The ball stretcher splits in to 2 halves with an allen key, so it's easy to fix around the scrotum. WARNING - this isn't for the faint hearted, but for guys who know how they want to get off look no further. Get hard, get in, get off! WE LOVE IT!
