The Fisher Space Pen Universal Ballpoint Refill was a revolutionary innovation that has been on board all manned space flights since 1969. Closer to home, its unfailing reliability has endless uses.
The ballpoint pen refill is pressurised so that it can write in all sorts of conditions and at all sorts of angles. It suits universal ballpoint pens and all Fisher Space Pens.
The refill has a fine point and is available in blue or black ink.
