Mark Two

A minimal and durable pocket pen
Mark Two is a custom machined, all-metal pocket pen small enough to take with you, but extends to a full length when in use. Built to last a lifetime, it comes with a special mini version of our favorite rollerball refill.
The black variant is currently on backorder for US orders and will resume shipping in a about a week.

Nothing extraneous.
Mark Two was designed to be minimal and beautiful. There are no logos or excess ornamentation, and the seam on the body (to unscrew and replace the refill) is completely hidden by a post-polishing process. The black cerakote sleeve has a slightly textured, matte finish, and the body is polished and smooth.

Take it with you.
Mark Two is quite short when sleeved, making it an ideal pen to carry in your pocket or purse. However, the magic happens when you post the sleeve on the body. Due to a clever bit of engineering, the pen elongates to a full length when posted. And when you are ready to cap it again, the body slides into the sleeve with a satisfying magnetic closure.

Made to last a lifetime.
If you’re going to be carrying a pen around every day, it needs to be durable. Mark Two is made entirely out of stainless steel. The outer sleeve is coated with Cerakote, a robust ceramic-polymer coating that wears beautifully. This pen should last a lifetime.

A mini version of the beloved Schmidt.
We were delighted to discover Schmidt makes a mini version of their amazing P8126 rollerball refill, identical in every way except the length. Perfect for a pocket pen. The Schmidt P8126 mini is what will ship with Mark Two, but our pen will also accept a Fisher Pressurized refill, which is very popular in the EDC community and a great option as well.

Best Space Pen Ever

Beyond highly recommended. I’ve been an avid Fisher Space Pen user for 30+ years. It has taken this long to find the perfect pen that accepts Fisher Space Pen cartridges. I ordered a second Mark Two just in case I ever lose the first one I bought. As I'm writing this, I think I better buy a third one.

Review on mark two

I like the pen, but I think it has several issues.
First, it is a heavy pen, I would like to buy another one if you make it with titanium. Second, the lid closure is unstable when it is in writing mode. It works, but not perfect.

Hi there! The pen is steel so the body can attract to the internal magnet :) Titanium wouldn't work in this instance. As for the sleeve closure when in writing mode: it is a press fit, so the harder you press, the more secure it will be. Check out this video to see it in action:

Mark Two

Beautiful pen. The only improvement could be some way to hold the cap on better on the end when in use.

Perfect On-The-Go Pen. Also Perfect At-Home-In-Sweatpants Pen. Just... Perfect Pen.

I was in the market for a low profile pen that I could clip into my Bellroy Field Notes cover, and after slogging through endless pen review websites (of which there are a shocking amount), I finally landed on the Mark Two.

My main criteria for this pen were:
1. I needed it to be portable.
2. I needed to not hate it when I used it.

I’m happy to report that the Mark Two has not only cleared my not-hate bar but has actually become my literal favorite pen. I’ve only had it for a few days, and I’m already annoying my wife with the subtle moans and approving nods I make while using this pen. It’s great while I’m out and about, and it’s great while I’m working at home. Even though it’s a “pocket pen,” it doesn’t feel compromised to me. I honestly can’t think of any context, really, where this pen wouldn’t be ideal. Maybe while driving on the freeway. Don’t do that. Pull over. And that’s not the pen’s fault.

All of this is to say that if I could have written this review using my Mark Two, I would have. But the Internet doesn’t work that way.

A great pen with lovely heft!

This pen is so satisfying in every way. I love how heavy it is, and the precision machining of its design is so incredible. It’s a good thing I work remotely and fiddle with this pen during meetings, otherwise people might tire of me snapping it shut in its awesome enclosure over and over again.

Oh, and for what it’s worth, it writes REALLY well, but I mostly just use it for snapping it open and shut.
