The last time they offered this design, I was sent three different pens that were nothing like the one pictured. A big fat thumbs-down from me! Even worse, the ink inserts arrived leaking and made a huge mess when I unscrewed the caps.
I bought a couple of these on a lark last time. Pen works fine (luckily, mine did not leak).
Read up on them afterwards - one outdoorsman/survivalist kinda ridiculed them. Said the purpose of them is to quietly carry something that you could use as defense… but try and get one of these through TSA and declare it’s just a pen.
I keep mine in the car. Need a pen in the car anyways.
