This offer includes the Holster with a key ring and belt clip. Pepper spray enables you to defend yourself while keeping a safe distance from an attacker. A one second burst to the face will cause temporary blindness and choking coughing and nausea-bringing the attacker to his knees. The active ingredient in our spray is Oleoresin Capsicum (O.C.) commonly referred to as red pepper. When considering which pepper spray is most effective one must consider the percentage of pepper being used and the heat rating of that pepper (measured in Scoville Heat Units or S.H.U.). At 180,000 SHU our Street Wise pepper spray is one of the hottest and most powerful in the world. The potency of this spray enables it to bring down even the most aggressive assailants. We offer a wide range of sizes for both civilians and police. This model can be carried in a holster, placed in the glove box of your car or on your nightstand or by the front door in your home. 5" x 1"
