Be prepared for any eventuality and always know that you can protect and defend yourself from an attacker. Mace's TakeDown OC-CS MK-IV Fogger Spray 4.23 oz gives you up to thirty one-second bursts of OC/CS formula at a range of 8-12 feet so you have plenty of opportunity to take down an assailant at a distance that keeps that person from doing any greater damage by stopping them in their tracks. Delivery of the spray comes in a fogger method. The Mace canister measures 6.25 x 1.50 and features a flip top cap that is spring loaded for safety. Please note that sprays cannot be shipped via air, nor to a PO Box - shipping is via ground service to street addresses within the continental US only.
