All-brass and steel construction with a tungsten carbide ballpoint tip, available in a range of colors and finishes. The 400 Series Bullet Space Pen is Fisher’s original and most popular design, known for its compact, durable build.

Its pressurized, hermetically sealed ink cartridge writes up to three times longer than standard ballpoint pens. Each pen is precision assembled, hand-tested, and backed by a lifetime guarantee against manufacturing defects.
