Pepper Shot is a 10% pepper spray (also known as OC spray) rated at 2 million scoville heat units and made with a very fine grain that is more effective than the coarser grains of most other pepper sprays. In addition to causing an attacker pain, Pepper Shot swells the mucous membranes, which makes breathing difficult, and swells the veins in the eyes, causing the eyes to close. These effects last 20-30 minutes and cause no permanent damage. All key chain sprays have quick-key releases. All sprays, except for pen (PS-3), have locking actuators.
