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 two colors: black or white. 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.

Rollerball pen does not work smoothly

The refill does not retract without pushing it in manually.

The pen is sturdy, writes so smooth, and is satisfying as heck to click. Wish I bought it sooner.

Excellent every day pen!

My new favorite pen and my every day go to. I am a mortgage broker and take notes throughout the day and this pen is perfect in my hand and glides very well. The construction of the pen is impeccable: very sturdy and the clicking mechanism is fun to play with. Its taken me a short while to get acclimated with the ink that comes with the Mark One, but it has been a great addition to my writing style. No need to press too hard as the ink does all the work. I ordered a black/copper, then ordered white/copper, and now I'm interested in the limited edition releases. These guys have a great thing going and i'm now a collector of their work.

Mark One hits the mark!

I really enjoy this pen. Bought the white with the copper. The ink writes perfectly, and the pen is comfortable and a bit wider than a traditional stick pen, which is great! I'll be purchasing in other colors.
