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.

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 nearly 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 ships with Mark Two, but our pen will also work with a D1 refill and a custom adaptor (coming soon!)

With or without a clip
Whatever suits you best.
We know tons of folks want a clip on their everyday carry pen, which is why we included one in the original design for Mark Two. However, in this new revision, we are now offering an option with no clip. If you prefer the clean, almost bullet-like appearance, clip-less is a great option.

Amazing Product. Amazing Company

The mark 2 was well worth the wait, anyone who has used the Fischer space pen will notice how the mark 2 is superior in every way possible. The tip wiggles like crazy on the Fischer; the mark 2 is rock solid. I don’t even consider the refill to be a downgrade. The Schmidt refill is much better. I mean, I don’t find myself in situations where I need to write underwater or upside down. Those are the only features of the Fischer that best out the Schmidt. Pen took a little while to get here, but like I said it was worth the wait. The company sent me two free refills for the long wait time. This pen is worth the price.

I know this sounds crazy, but this pen changed my whole journal habit

I used to carry a small pen (Fisher Space Pen) in my pocket notebook, but I didn't end up writing much in it. I thought maybe writing in it just was a sometimes thing for me, but after getting this pen I realized the whole time it was just difficult to write with the Space Pen. I still wanted a small pen that fit in the pocket notebook so I tried this out and I legit use it for long stretches every single day. I also ended up write a long form journal now instead of typing it into my computer. Pen and paper really give you more time to think and be intentional. This pen is a big part of why that's what I do every day. Thank you!

Love this pen

Feels good to hold something this well made and to write with it. Been a fan of Studio Neat's since the first Glif and this pen doesn't disappoint.
