It is a tactical pen with an led flashlight as well as a window breaker. It comes in gift quality and the contents inside are nicely secured with a dense foam insert. The light is average brightness for its size.

The self-defense tip is designed to be always out without a cover, so that you can use it in one move out from any situation. It is detached as the ballpoint only, making it practical for daily use. The breaker point is sharp and sturdy enough to work as intended with a metal shaft that should hold up to said function.
