Each Pen is precision assembled, hand tested, and sold with a lifetime guarantee against all manufacturing defects. But that’s not even the coolest part; this pen has so many unique capabilities, Fisher Bullet Space Pens write in any temperature (-30 to 250 degrees F) and at any angle. Including upside down, not relying on gravity to write, it’s a Zero Gravity Pen.
The secret behind all of these capabilities is the ink cartridge itself. The refills are hermetically sealed, pressurized with nitrogen gas, and feature a tungsten carbide ballpoint tip fabricated with the same extra hard metal that is used to make armor-piercing ammunition.
