What your attacker doesnt 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 two 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 are included. Safety on/off switch. Available in Black and Pink. LIFETIME WARRANTY.
