Good EDC pen
Despite the advertisement that it works underwater, that may only be true for all temperatures at 1 bar. It may not work when submerged in supercritical water at high pressures and temperatures above 110C. It may also freeze in antarctica or in siberia. In most situations you are likely to encounter, it writes. Not amazingly well, and a gel pen or a fountain pen will give a more satisfying result on good paper (the result is slightly better than with a pencil), but it will work on basically every surface and in the vast majority of situations.

LOVE it!
Subtle differences over the standard bullet space pen are SO worth it! The flat top make it easy to know which end is which and make it slightly shorter when close - which is the whole point, pun intended, of this pen style. The clip is a MUST HAVE! Without the clip it's easy to loose - rolling off everything and/or slips through pen loops. Plus this is fixed, not a slip-on add-on. The matte black finish is very easy to hold, no fingerprints, not inclined to slip out of pockets or loops. Very stealthy! If I do ever loose it, I will definitely buy it again. If gifting, it comes in a really nice plastic case - great for repurpose to hold small items.
