Each unit also includes UV dye for later identification of the subject by law enforcement. The unit allows for one hand operation and can be used to provide multiple blasts. A suspect will be immediately affected with burning skin, coughing, watery eyes, runny nose, difficulty breathing but will have no permanent injuries. It is both non-toxic and non-flammable. This is a full pen canister of 17 percent pepper spray that blends perfectly in your purse or bag. They will never know you are so well protected. Keep away from children and do not store in high heat.
