5 7/8" overall. Stealth black anodized aircraft-grade aluminum construction with interchangeable stainless tip, lanyard hole and stainless fittings. Features O-ring gasket sealed cap that now can be screwed onto the back of the pen's barrel. O-ring ribs on the body for secure, comfortable writing. Black ink. Stainless pocket clip on cap. The cap provides an almost flat surface that allows the thumb to conveniently "cap" the end to prevent the grip slippage during dynamic use with a hammer-fist grip. One end is pointed, which could be used as an effective defense tool. Also includes a black polymer interchangeable stylus tip. Bulk packed.
