Minimal
It’s literally seamless.
Mark One has a completely seamless design, which was quite an engineering feat. The pen has no excess ornamentation or logo, and comes in several colors. The metal plated nocks provide a nice little accent to each, and give Mark One a sophisticated look without looking overly tactical.

Durable
Made to last a lifetime.
Mark One is incredibly durable. It is made entirely out of metal, including the custom click mechanism. The pen is coated with Cerakote, which is an extremely durable ceramic-polymer coating (technical specifications for Cerakote). It gives the pen a really nice, matte feel. This pen should last a lifetime.

Retractable
A completely custom click mechanism.
There are many off-the-shelf click mechanisms we could have used, but none of them were quite right for what we wanted, so naturally, we made our own. It is made entirely out of metal and, as far as we know, it is the only all-metal mechanism on the market that has an actual “click” action. It is satisfying as heck to click.

Refill
Built for an amazing rollerball refill.
Mark One ships with our favorite refill, the Schmidt P8126 rollerball. This is a fantastic cartridge; the ink flows smoothly and dries quickly. However, Mark One will accept any Parker-style refill, which means there are many options for pen cartridges that our pen will accept. This list from Well-Appointed Desk is quite comprehensive.

No asterisks.
This pen is great, the weight of the aluminum is prefect - I wasn’t interested in the steel since I write 9-10 pages of notes a day in my job; I felt the steel would be cool at first then probably fatigue my hand. The click is satisfying and the construction is excellent. I say NEAR perfect because I understand not having a clip - it would throw off the aesthetic and look cheap…but on a minimal pen please add a minimalist “bump” even a tiny almost not noticeable bump would prevent the pen from rolling off my desk. I use notepads and this pen is constantly rolling somewhere and I don’t want use a pen holder - it clutters up my pristine office set up. A small bump could be implemented with no sacrifice to the aesthetic whatsoever. Make one and I’ll buy it!
I’m a cop. One of the only pieces of equipment that we carry every single day that we can actually 100% select our own preference is our pen. As such, I have had and many of my coworkers have carried several different manufacturers, and styles. Most choose something ‘tactical’, that actually is just a flashy gimmick. I recently gave the Mark 1 a try, and I love it!
It fits perfectly in my shirt pocket without the use of a pocket clip. I thought that I would need a clip, so I ordered one that does fit the pen, but I find that it isn’t needed and the pen feels soooo comfortable in the hand without the clip. Once it’s in the pocket, it sticks out enough that I can easily retrieve it and while it is visibly obvious that it’s a quality pen, it is more subtle than a high-tech, futuristic looking tactical pen that I see so often.
It is this understated, but obvious high-quality that I have been looking for.
Outstanding products and work excellent!
I’ve been using cheap free pens from conferences and my dentist office for a decade now. Finally decided that I should have nice pen, and I do not regret it one bit.
This makes me excited to pick up a pen and write/draw, even if just to doodle.
At first, I thought this was a lot of money to spend on a pen, but the technology is amazing
