Inka Pen

The 'write anywhere' pen, ideal for clipping to your keys - never be without a pen again!
This pen is fabricated from high-strength aerospace-grade materials.
Following strict specifications, the stainless steel barrel is hardened, CNC machined, centerless ground then laser engraved.
Lightweight, watertight and built to withstand harsh environments. The pressurized ink cartridge ensures the pen will write wet or dry at any angle, any temperature, and any altitude.
Developed in Boulder, Colorado and is U.S. and internationally patent-pending.
The Inka Pen is designed and built to last a lifetime.

Inka refills are built to perform at any angle, any altitude, in all weather conditions, and even underwater. The Inka PDA Stylus is built from Delrin, the material specified by most major PDA manufacturers for use in stylus tips because of its natural lubricity and durability.
