This supremely sturdy steel CBT device is designed to hold the balls in place while you turn the screw to apply pressure. Even the threat of such a squeezing is likely to cause a wince in the hardest of subs, and this heavy duty apparatus is more than capable of backing up any threats you care to make.
Simple instructions for use:
1) Unscrew the bottom ring on the flask using the included allen wrenches, and insert testicles.
2) Re-attach the ring, trapping the balls in the flask portion of the device.
3) Turn the vise screw slowly clockwise, until desired pressure is obtained by lowering the crushing press.
4) Watch them squirm!
