Sadly the world is not always the safest place to be in so you need to protect yourself. KNUCKLE BLASTER is a 950,000 Volt stun gun with batteries and a magnetic leather holster that will give you a punch with power. You just need to touch the attacker and they will instantly be repelled and give you much needed time to get away. A little longer contact will make them very disoriented and after some seconds they may drop to their knees. It uses 2 Lithium batteries (included) and comes with a FREE nylon belt holster ($15.00 Value) designed to allow quick access and deployment of this amazing stun weapon. This is the real deal. Stay safe.
