Inka Extreme Conditions Pen First Look (Outdoor Retailer Winter Market 2005)

If the Inka pen has not won a design award, it should. It is a marvel of precision-engineering and attention to detail, and truly feather light. The cartridge is pressurized so that it can write at any altitude, angle, temperature, and underwater – and it writes smoothly. The pen debuted at this OR show and is the first offering from entrepreneur and designer Greg Adelman, an optical engineer based in Boulder, Colorado.
