Before the eyes of an innocent victim, you swing the cord of this HolzKnobel stick into the button hole. Afterwards the victim will try in vain to remove the HolzKnobel stick again from the button hole and after some time will despair. Also spectators, who saw everything, will try to help in vain. With this HolzKnobel staff you can have a lot of fun with your "victims" and spectators.
