Steel Flask Ball Crusher

Secure the removable ring around the scrotum, then place the balls into the hollow chamber. Use the included hex key to lock the ring onto the end of the chamber and their boys are now enclosed in a cool steel cylinder. Slowly turn the T-handle, a steel disc inside the Press Chamber descends, gradually reducing the amount of space inside the cylinder. Warn them with a bit of gentle pressure, then maybe tighten things down some more for some more serious discipline.
