Black ink ballpoint pen comes inside plastic case.
The original Bullet Space Pen was conceived in July of 1948. Made with an all brass body, the inner ink component of the Bullet is pressurized, assuring smooth writing on virtually any surface! The sealed ink cartridge is pressurized at about 45 pounds per square inch and contains a visco-elastic, thixotropic, solid-gel ink. The result is a ballpoint pen that will write dependable smooth upside down, underwater, over grease, in extreme cold and hot temperatures and has an estimated shelf life of 100 years. Multiple body colors and ink color refills available.
Pen dimensions: Approximately 3.8 inches (9.7 cm) long when capped, 5.3 inches (13.5 cm) from tip to end of cap when cap is posted on back of pen, and 0.4 inches (10 mm) in diameter.
