It feels kind of weird writing about these products after Nock.co is no more. And I have gone back and forth many times on if I should write about them or not.
I decided on yes.
Hightower as the first Nock.co product I got. It is a great pen case. I used to bring it everywhere for years. My setup at the time was to have my current Field Notes + two spares in it (or my previous + current + a spare). Plus two fountain pens, a gel pen and a ballpoint pen.
This was back when I was a student, and because of carbon paper I always had to have a ballpoint.
It was great for this kind of setup, and served me really well for a very long time.
