Nitecore NTP21 Tactical Pen Aluminium Black

The NiteCore NTP21 tactical pen is a solid tactical pen with glass breaker. The pen has a pressurized Schneider refill. As such you can write anytime and anywhere, even underwater, in extremely hot or cold weather and even upside down. The cap is kept in place with the screw thread. The back of the pen is also enhanced with these coarse threads. So when you use the pen you never have to hold the cap, you simply add it to the back of the pen. Because of the rubber O-rings the pen is sealed off and waterproof to make sure it will always stay in great condition.
