It looks like an expensive Executive pen, but looks can be deceiving. This is actually a solid high-craft aluminum personal security and self defense Tactical Pen from Azan. The body is made from high-craft aluminum and is heavy enough for proper speed and mass. Upon strike, the sharp pointed end of the self defense weapon will concentrate a painful impact force.It is a powerful means of defense. If you ever get caught in an emergency situation, the point of the pen can pierce glass, busting out a window or door. The pen writes in black ink and the ink cartridge is replaceable. Comes packaged in a color graphics box and makes a great gift for anyone of age.
