These 2 and 4 ounce sizes come in both stream and fogger models. In addition to causing an attacker pain, Pepper Shot pepper spray swells the mucous membranes, which makes breathing difficult and swells the veins in the eyes, causing the eyes to close. These effects last up to 45 minutes and cause no permanent damage. All sprays have locking actuators for extra safety. All Pepper Shot brand pepper sprays have identifying dye. These larger size pepper sprays are great for in your home, RV, or when you need to carry just a bit more protection. Pepper Sprays can not be shipped to New York, Massachusetts, or Wisconsin.
