Two-Pack Refill for Fisher Space Pens

This two-pack contains black fine-point pressurized cartridges compatible with most Fisher Space Pen models, excluding the Infinium and stick pens. Each refill uses a sealed, pressurized ink reservoir that feeds the ballpoint without relying on gravity.

Suited for Harsh-Condition Writing.

Workers who need reliable marks at any angle, underwater, through grease, or from -34 °C to 121 °C will find these cartridges dependable. Buyers whose pen is an Infinium or stick model must look elsewhere because the refill will not fit those designs.

Pressurised Cartridge Technology Decides Fit

The hermetically sealed, gas-pressurised cartridge is the single specification that determines whether the refill works in your pen; if the barrel accepts standard Fisher pressurised refills, these two black fine-point units will install directly.

Questions about this item

How does the fine point feel when writing upside down or on a wall?

The pressurised cartridge feeds ink without gravity, so the fine point keeps flowing smoothly when you write upside down, vertically or at any odd angle.

What pen bodies accept this SPR4F-2PK refill?

It fits every Fisher Space Pen model except the Infinium and stick pens, so most standard Fisher barrels will take the cartridge directly.

How much space does the two-pack blister occupy in a drawer?

The sealed pack measures 6.73 by 2.56 by 0.35 inches, a flat rectangle that slips easily into a shallow desk drawer or pen case.
