This steel CBT device acts as a ball stretcher, torture device for the scrotum, and a ball collar. Those functions are contained in one simple to use device. Simply slide it into place and secure it with the built-in lock. The larger size allows for ultimate restriction and security on bigger girths. Four pointed screws line the inside of this devious piece, which can be twisted to apply more pressure. The front features a steel O-ring, so you can lead your slave around with a leash, or even add extra weights. This item can be used independently, or in tandem with other products.
