From the Kickstarter page:

Perhaps unsurprising if you know us, but our design goal from the beginning was to design a pen that was both minimal and beautiful. Mark One has a completely seamless (literally) design, with no excess ornamentation or logo. This seamless design was quite an engineering feat, and involved designing a custom mechanism that can screw in from the back. The pen comes in two colors: black or white, which both have a slightly textured, matte finish. The metal plated nocks provide a nice little accent to each. We wanted the pen to be sophisticated without looking overly tactical or masculine.

I recently took up journaling and this is exactly the type of pen I’ve been looking for. Something that’s minimal, durable, retractable, and made by a group of people that care deeply about good design.
