Description Made from aircraft-grade aluminum for extreme strength and portability. This pen is light enough to keep in a pocket or bag but strong enough to use a defensive striking tool or weapon. The handle has a threaded design to ensure a strong, non-slip grip that you can feel. The pen includes a hard and sharp glass breaker tool that can be used to break a window in an emergency. The heavy-duty clip is sturdy and tight allowing you to attach it to your shirt, pant pocket, backpack or notebook. Twist the pen body to deploy a standard ballpoint pen that writes smoothly and reliably. The package includes the pen along with a single ink cartridge. Replacement ink cartridges are readily available on Amazon and other office supply stores.
