Made in Boulder City, Nevada, this brass pen with its hard chrome plating pen has a comforting weight that rests reassuringly in your hand as write. It utilizes a two button click mechanism: the top button extends the refill while a side button retracts it. The knurled grip keeps your fingers from sliding and the clip easily extends over heavy fabric. As a Fisher Space Pen, it writes at any angle--including upside down--and in extreme heat and cold. It's also guaranteed to write on almost any smooth surface, whether wet or greasy or underwater, as well as on coated paper or photographs or x-rays. The thixotropic ink in the pressurized reservoir writes three times longer than your standard ballpoint, making it a go-to choice for alpinists and divers, paramedics, construction workers, and astronauts. This is the pen Buzz Aldrin carried to the moon in 1969 and has been used on all NASA Apollo and Shuttle missions since, as well as the International Space Station, Russian Soyuz and MIR space flights, French ARIANE Space program and the Everest North Face Ski Expedition. We highly recommend it for your next expedition, whether that's Antarctica or the coffeeshop 'round the corner!
In the 1950's there were dozens of ballpoint models, and nearly every one took a different refill. So in 1953 Paul Fisher invented the "Universal Refill," which could be used in most pens. But he didn't stop there. After much experimentation he perfected the refill using thixotropic ink; the trick was to have the ink flow when you wanted it to, and not to flow the rest of the time, a problem Fisher solved.
