As we all know, I have a slight (ok, maybe more than slight) pen obsession. I'm also a big proponent of self defense. So, when I saw this tactical pen that included the ability to defend myself and write, it was a no brainer, must have purchase. I absolutely love it. It has definitely become one of my favorite pens and goes everywhere with me. I love having a pen and self defense device combined in one. The pen also writes very smooth. I was worried about how it would write and if it would be too heavy but that was definitely something that I didn't have to worry about. I can't say enough good things about it! Hopefully I never have to use it for self defense but if I do, I'll have it.
