A cell phone can be a real lifesaver in an emergency situation, but now it’s also a self defense weapon. The Spraytech Self-Defense iPhone Case includes a detachable pepper spray cartridge. Normally I question the practicality of “purse weapons” (like lipstick tubes with a hidden knife inside) but the idea behind this product seems pretty sound. Not only do you always have your phone nearby, you might already have it in hand to call 911 if you’re in a dangerous situation. (Unlike the situation where someone attacks you and you go, “Wait, wait, I have to put some lipstick on first.” and then you stab them.) If you’re a cynic you might be saying “But couldn’t you accidentally mace your friends while updating instagram?” Nope. The case features multiple safety mechanisms so you’ll never accidentally trigger the spray.
