The new Streetwise Protect-Her Tactical pen not only writes great but it can be the right product to protect you from an attacker! It is a close-quarters self-defense weapon, a bright LED flashlight, and a fine writing instrument that can also be used as a glass-breaker in case of an emergency. The ink pen uses standard refills and is protected by a removable pressure point cap which can be used for self-defense. The other end features a bright LED light with a DNA Collector Tactical Edge. Requires one AAA battery; a Duracell brand battery is included. The Streetwise Tactical Pen is made of the highest quality components and comes with a lifetime warranty. The Streetwise Protect-Her Tactical Pen not only protects women from attackers but also protects their health, as a portion of the proceeds goes to fight breast cancer.
