A compact 20 ml RAM Defense Pepper Fog, small enough to carry in a pocket or in a small bag so that it is always at hand. It sprays a fog that spreads over a wider area. It uses OC (oleoresin capsicum), the active ingredient taken from very hot chilli peppers, which causes intense burning, watering eyes and coughing on contact so that you can get away. RAM Defense describes its sprays as non-toxic and non-flammable, with the main effect lasting at least an hour. Supplied as: tin only, no blister pack. Because the can is small it holds only a few short bursts, so treat it as a get-away tool and practise drawing it. Aim at the face, then move away. Keep away from children and heat.
