Inspired by the aerodynamic lines of spacecraft, the X-01 is precision-machined to exacting tolerances from a solid piece of brass which give it a distinct feel and superb balance in the hand. 

The X-01 features a solid metal twist mechanism, also precision-machined, for excellent reliability over many years of use.

The X-01 is a capless rollerball (Schmidt P8127 refill), which writes smoother than a ballpoint as it uses water-based ink instead of oil-based ink. The X-01 can also be used with Parker-style refills.

Please note that the brass is uncoated and will darken with age, forming a patina unique to each user.
