We think that Pen World magazine said it best in its review of the Inka pen: “Small and ingenious, this pen belongs in the same class as our greatest icons of strength in compact packages: the Porsche 911, the Swiss Army knife, Sugar Ray Leonard.” Whether you are boating, camping, hiking, traveling, writing upside down (if you're an astronaut), or simply want a dependable pen at all times, the Inka pen delivers quality and durability. 

The creator of this pen—an engineer—spent years designing and developing instrumentation for Scripps Institution of Oceanography and manufacturing de-mining equipment for the U.S. military and NATO. While at Scripps, he developed the concept for the Inka Pen because he saw a need for a reliable pen that could function in all sorts of conditions. In addition to top-quality materials (stainless steel and carbon fiber), it has a ring to attach to your keychain and a stylus tip for touch screens. The blue ink is waterproof. It can be quickly unscrewed for quick use, or converted to a full-size writing instrument.
