The Nitecore NTP21 is a multi-functional tactical pen which combines a useful writing tool with a glass breaker for emergency use. The glass breaker is a tip made from Tungsten steel which is remarkably robust and can provide a means for escape in a critical situation. The pen itself is a high quality Schneider gel ink which is quick drying, waterproof and fade-resistant. 

Compact and lightweight, the pen weighs just over 25g and is made from durable aluminium with a black anodised finish, for impact and corrosion resistance. Featuring an ergonomic design, the NTP21 is comfortable to hold and has an anti-skid thread to increase friction and avoid sliding when in use. 

The multi-purpose pen comes with a rigid clip which allows for easy attachment to your pocket, shirt or backpack. In addition, the NTP21 includes a removable pen cap which can cover either end when not in use. For example, when using the pen the cap can cover the glass breaker end and vice versa.
