The Muscle Ball Stretcher from Sport Fucker is by far the most comfortable silicone ball stretcher available on the market!
What makes the Muscle Ball Stretcher from Sport Fucker so comfortable? First, the design. It's nice and thick and adds a good amount of weight to your sack, without a constant pain that you have with metal ball weights.
But more importantly, All New Silicone is used to make these Muscle Ball Stretchers.
You have to feel that they understand. Words don't do the material justice, but to try we would describe the new silicone as silky smooth, elastic and firm.
