The Life Pager's patented design resembles an ordinary pager but contains two canisters of police strength, two million S.H.U. pepper spray. It may be clipped to a purse, belt, or a vehicle's sun visor making it easily accessible. Disguising your pepper spray as a common pager provides you with the element of surprise needed to safely defend yourself against an attacker. Measures in at 3 one-quarter inches x 2 inches x 1 one-quarter inches.
