Fisher Space Pen Stowaway – a compact pen for extreme conditions

The Fisher Space Pen Stowaway is designed for people who travel light. Its body is only slightly larger than the ink cartridge.

When folded, it fits anywhere – in a pocket, wallet or organiser. The clip allows it to be easily attached to the edge of a pocket or rucksack.

Space-tested technology

Every Fisher Space Pen is precision-assembled and hand-tested. It comes with a lifetime guarantee against manufacturing defects.

Works at temperatures ranging from -34°C to +120°C
Writes underwater and in zero gravity
Writes at any angle
The ink does not skip or leak
Writes up to three times longer than standard ink

Construction and materials

The body is made from anodised aluminium. The construction also includes brass and steel components.

The tip of the refill is a tungsten carbide ball. The refill contains a pressurised nitrogen cartridge which forces the hermetically sealed thixotropic ink through.

The ink is solid when at rest and liquefies when writing – which is precisely why the pen does not leak or smudge.

The perfect gift for a man or a woman

The Fisher Space Pen is a suitable gift choice for people in various professions – doctors, lawyers, military personnel, police officers, teachers, business leaders and A-level students.

It’s also suitable for everyday use in the car or in your bag – it’s reliable in summer and winter, whatever the conditions.

History of the Fisher Space Pen

During the early NASA missions, astronauts used pencils. In 1965, NASA purchased mechanical pencils at a cost of $128.89 each, which caused public outcry.

Paul S. Fisher of Fisher Pen Co. developed a ballpoint pen with a pressurised ink cartridge entirely at his own expense – at a cost of around $1 million. It worked in zero gravity, underwater and at extreme temperatures.

In 1967, following rigorous testing, NASA equipped the astronauts on the Apollo mission with these pens. Approximately 400 were purchased at a price of $6 each.

In February 1969, the Soviet Union also purchased 100 Fisher pens and 1,000 refills for the Soyuz spaceflights. To this day, American astronauts and Russian cosmonauts continue to use them.
