Tight or loose, that's up to you - and of course, dependent on how well your man is behaving. Our Ball Crusher will make him want to really obey you and is made of sturdy, high quality metal. This large toy's jaw is very adjustable at 4" tall and 3 1/4" in width and is very hefty at over a half pound (.65 pound to be exact), so it also acts as a weight. Overall, with the thumb screw, this polished metal clamp is up to 9 1/2" in length when the thumb screw is backed out. Cock & Ball torture fans will really love this device. If you really want to see him beg, just try our crusher, and screw it down a few notches!
