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.

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.

Great Pen

I love my new Mark One and it has instantly become a mainstay and a workhorse on my desk.

The pen is light and well balanced. The clicker "knock" mechanism is smooth and satisfying. The pen is designed to take Schmidt's excellent short capless rollerball refill. These water based ink rollerball refills (P8126 and P8127) are, perhaps, the closest a rollerball can come to the smooth feel of a fountain pen.

Like many people, I constantly need to jot down a quick note or two during a phone call or while doing some research. A good rollerball is perfect for this task. By using a click mechanism easily operated with one hand, the Mark One has proven more convenient than twist-actuated or capped rollerballs. At the same time, it provides a more pleasant writing experience than a ballpoint pen (which traditionally uses a paste based ink).

My Mark One sits on a walnut double pen tray. I plan to add another Mark One (in a different finish) for the other slot and to fill it with a different color refill for some instantly available variety.

Excellent writing Utensil!

This pen is perfect. Sleek but sophisticated design. It is well balanced and a solid manufacturing of a pen. I highly recommend the Mark One pen.

Best pen ever

quailty is 10/10. weight, materials, everything. sometimes the ink gets stuck a little but not a big issue

Excellent but some notes

Love it. Only things I would change are slightly longer (feels a bit small in my hands) and option to come with red ink. I bought red refills since all I write in is red.

The roundness making it roll everywhere can be annoying but it is a direct consequence of the minimalism and style I love. So, not sure how to fix that.
