This pen was born from the need to have not only a quality writing instrument but also a tough, durable self-defense tool that you will have with you at all times. Check out these features that make this tool a must have for anyone who is concerned about discreet personal safety. All of our pens use the Fisher Space Ink cartridges (BOLD Point full size refills pn# SPR4B) due to their unique design of being able to write underwater, over grease, upside down, in extreme temperatures, zero gravity and last longer than the average pen and can still be purchased at your local office supply store when you need a refill. This is important to us because it covers all the bases for our demographics of customers in the Military, Medical, Firefighter, Law Enforcement and the everyday work force fields.
