Mace Personal Pepper Spray uses a powerful formula that causes respiratory distress and coughing, impaired vision and intense burning sensation on the skin. The formula has a UV dye that leaves a long-lasting residue that supports investigation and identification efforts. It includes a flip-top safety cap to prevent accidental discharge. This product contains 20 bursts with a spray range of 12 feet, recommended to replace and refill after each use. Put your thumb under the flip-top safety cap and press the red actuator button to spray.
