The Mace 10% Pepper Foam Magnum combines high-strength capsaicin, a foaming agent and ultraviolet dye for the ultimate self defense spray. The foam covers your attacker's face, reducing their ability to see and targeting their nose, eyes and mouth for maximum effectiveness. The UV dye make it easier for law enforcement to identify your assailant. The canister contains enough spray for 10 one-second bursts with a range of six to ten feet. It also features a flip-top safety cap that prevents accidental discharges, making it safer to carry around without preventing rapid deployment in an emergency.
