However, its primary focus on self-defense might make it less appealing for those solely seeking a writing instrument. The black color and tactical design may not suit everyone's aesthetic preferences. The limited lifetime warranty adds to its credibility, ensuring long-term satisfaction. This pen is a great gift for men who value both practicality and safety.

However, some users might find the extra weight to be a drawback if they prefer lighter writing instruments. The pen's writing functionality is practical for everyday use, but being a tactical pen, it might not provide the smoothest writing experience compared to specialized pens. With a high customer rating of 4.6 stars, it seems to be well-regarded by users for its robustness and utility. This pen set is particularly well-suited for men who want a reliable writing tool that doubles as a self-defense device.
