Description Style: Cap Slides On & Off Finish: Matte Black with Clip Length: Open – 5.25" Closed – 3.75" Cartridge: Our Famous PR-4 Black Ink Medium Point Packaging: Moonscape Gift Box and an Astronaut Sleeve For over 50 years, Fisher Space Pen has been proud to have our technology approved and used on every crewed flight into space since 1967 with NASA. Today, space exploration is achieving unimaginable accomplishments, while NASA is continuing to push the envelope of what is possible, in space. Finally, our fans have the chance to collect their first Bullet Space Pen donning the NASA Meatball logo! When closed, the Bullet Space Pen is the perfect size to carry in your wallet, pocket, purse, car glove box, organizer or toolbox. When opened it’s a full-sized, evenly balanced writing instrument. Each Bullet Space Pen will write upside down – at any angle, under water, through grease, in extreme temperatures (-30 to +250 degrees F), on almost any surface, three times longer than the average pen, and of course in the gravity free vacuum of space. The original Bullet Space Pen was conceived in July of 1948 by Paul Fisher, who was soon machining a new pen design shaped from solid aluminum. This became our first Fisher ball point pen, the #400 Bullet Pen, and arguably the most popular pen of the twentieth century. Cited as an outstanding example of industrial art, the classic design of the Fisher Bullet Pen has a place in the permanent collection in the New York Museum of Modern Art. The Bullet’s timeless styling has been the topic of many art books and magazine articles. Often imitated but never duplicated, the Fisher Bullet Space Pen continues to be our most popular pen design.
