Let your imagination run wild. Turn the eyebolt handle to increase the pressure and make your subject obey your every command. This crusher can not only be used for CBT, but we’ve gotten some feedback from customers saying there are many other uses (balls, cock, breast, lips, etc…) For extra added excitement, you can also add rope or weights to the eye bolt of the crusher. We are including 2 sets of spikes (1 set of pointed and 1 set of rounded/flat). The spikes are also adjustable using the supplied hex wrench.
