Space Pen Saver

"I bought a seven-dollar pen because I always lose pens and I got sick of not caring."
-Mitch Hedberg

I love space pens, because they're like pens, but spacier. For years, I would lose my bullet-type pen because it would slide out of my pocket or roll off a surface. So, I designed the Space Pen Saver with my friend ThePlanetMike. The first prototype came out more than 7 years ago, and I've been testing it ever since. I can report that I still have the space pen and original prototype saver. I lost the original file, but since I had the prototype it was easy to reproduce.

I can report that the Space Pen Saver does not interfere with basic pen twirling tricks.
