Mace gives you a big bang for your buck in a small package when it comes to self-defense. Available in 2 sizes (1.8 oz or 3.31 oz). These sprays deliver 15-25 stream bursts of OC pepper heat at a range of 8-12 feet, so you have plenty of opportunity to take down your assailant at a safe distance before they get close enough to do any real damage to your person. Please note that pepper sprays cannot be shipped via air, nor to a PO Box – shipping is via ground service to street addresses within the continental US only.
