THE RUNT is easily concealable, and virtually undetectable in the hand of a woman or man. What your attacker doesn't see will drop him like a roach who has ingested a little too much Black Flag. The Runt uses new cutting edge micro-technology to deliver super powered protection from a palm sized paladin. There are three voltage levels so you can pick your attackers poison. You can carry the Runt in your hand or pocket. If you would like to wear it like a pager there is a heavy duty nylon belt loop holster included. Batteries included. This unit is perfect for women of all ages, and works for men as well. Safety on/off switch. LIFETIME WARRANTY. Available in three voltages: 2.5 million volts, 3.5 million volts and 4.5 million volts.
