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.

4.5/5 Rounded Up

Best part of the pen is the sleekness of it. The minimal design makes it a nice writing experience. Add in the nice weight of the pen and it makes the writing experience really enjoyable. It feels like it will last a very long time so the price is easier to swallow. The reason for the slightly lower rating, they really talked up the click of the pen and it’s very nice but the expectation was higher. Time to time there is a slight movement in the tip of the pen when writing, not a large deal but I wish it wouldn’t move. Overall I would purchase again, and it makes writing more enjoyable. It makes writing feel more important too, that’s an underestimated aspect of the pen.

Almost the perfect pen

The sleek appearance and the smooth writing makes this pen one of my favorite, but it is missing one important feature. A clip. I know there is the Mark 2, but I like the retractable feature of the Mark 1. Any way to design a clip to add to this pen?

My favorite pen ever

I’ve had this pen for 4 years and it still works perfectly and writes beautifully. The click is so satisfying. Hopefully I’ll never use another pen again

Awesome

Been a couple weeks now and absolutely love the Mark One. I love the weight, but it is heavy and may not be everyone’s cup of tea. Writes really nicely, has a great feel to it, and just like the ad says, it’s a very satisfying click.
