Fisher Space Pen SUF Universal Ball Point Refill

Fisher Space Pen SUF Universal Ball Point Refill

Pressurised Refill

This refill still has the same technology as the larger PR refill range so can still write in extreme conditions, upside down, under water and even in space.

To fit the TAG/S, TAN/S and Q4 multifunction pens. Available in Black, Blue or Red. Fine only.

Will also fit many other brands like the Cross Tech3+, Tombow XPA and PenAgain.

Please note: The Universal Cartridges contain a much smaller amount of ink, they write about 1200 feet depending on your writing style, as compared to our regular PR Cartridge which should write more than 12,000 feet depending on style and surface.

Nearly all ball point pens have a gravity fed ink refill therefore they soon stop working when you write horizontally or upside down, however the Fisher Space Pen refill does not rely on gravity as the cartridge is pressurised to 35psi. The ink used has been specially developed to have a thicker consistency. The rolling of the tungsten carbide ball thins and distributes the ink smoothly, giving you a better and more consistent ink flow. Common problems associated with normal ball point pens such as shelf life and leakage are eliminated. The Space Pen refills will write at any angle including upside down, on greasy paper, on wet paper and even under water. They will write in extreme temperatures from -34c to +120c.

The Universal Space Pen refill which is used in the Q4 is much smaller but will still write for approximately 350m. These will also fit many other brands of multifunction pens such as Cross and Tombow.
