The perfect pen to match an already great notebook.
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.

I have purchased better pens for less. I was not impressed. Way to pricey.

Simply the best

I love a great pen. My friends and family think I’m crazy for always spending a little more money for a great pen to write with. Whether it’s for work, journaling, studying; I always appreciated writing things down and there’s no better feeling than to write with a good pen. I had done some research and came across Studio Neat and decided to purchase the Mark One. It did not disappoint. I look forward to every word or note that I have to write down and it has actually boosted my productivity. I love the product and highly recommend the notebooks as well. I’m a customer for life and will not ever write with another pen for as long as I live.

My new go-to

If you are reading this, you are a pen guy like me and this pen is my new go-to standard. Excellent fit and finish and it feels just right in your hand. Aside from all that, the performance of the ink and writing form is outstanding. Worth every penny (and thier customer service is outstanding to boot)!
