Make your sub beg with the heavy steel Ball Press Chamber. Secure the removable ring around their scrotum, then place their 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. Now you are in control! As you slowly turn the T-handle, a steel disc inside the Press Chamber descends on their balls, 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. Get instant compliance to your slightest demand, every time, with the steel Ball Press Chamber!
