This adjustable leather penis and testicle strap contains internal metal spikes on either strap that will hurt any flaccid penis, and if even a hint of arousal occurs it won't last for long as the rivets dig into the penis and the testicles affecting lots of pain. The two leather straps are connected via a central strap. Both the penis and testicle straps have adjustable press stud closures. Material: leather, metal.
