No cap, no fuss. It can be operated with one hand and fits easily into a pocket, wallet or organiser.

Why the Fisher Space Pen is different from ordinary pens

Every Fisher Space Pen is hand-tested and comes with a lifetime guarantee against manufacturing defects. It’s reliable in extreme conditions:

It works at temperatures ranging from -34°C to +120°C
It writes underwater and in zero gravity
It writes at any angle, including upside down
The ink is thixotropic – solid when at rest, liquid when writing
Does not leak or run out
Writes up to three times longer than ordinary ink

Construction and refill

The barrel is made of brass and steel with an aluminium coating. The refill tip is a tungsten carbide ball – a material of exceptional hardness and durability.

The SPR4 refill contains a pressurised nitrogen gas cartridge. A small metal cylinder presses against the hermetically sealed ink, allowing you to write in all conditions. The pen is compatible with all Fisher PR refills.

A gift for a man – a practical and prestigious choice

Fisher Space Pens are an excellent gift idea for men – and for women in demanding professions. They are suitable for teachers, doctors, lawyers, military personnel, police officers, business leaders and school leavers.

They can be used every day – in the car, in a handbag or in a rucksack. They don’t freeze in winter or leak in summer. The clip allows them to be attached to a pocket or the edge of a rucksack.

The pen comes in a gift box – ready to give without any extra wrapping. 🎁

History of the Fisher Space Pen

During NASA’s early missions, astronauts used pencils. For the Gemini programme in 1965, NASA purchased mechanical pencils at a cost of $128.89 each – an expense that sparked public outrage.

Paul S. Fisher of Fisher Pen Co. developed a ballpoint pen suitable for the space environment – without funding from NASA. The company invested around $1 million of its own funds, patented the product and offered it to NASA in 1965.

Following rigorous testing, in 1967 NASA equipped the astronauts of the Apollo programme with these pens. Around 400 were purchased at a price of $6 each. In February 1969, the Soviet Union also purchased 100 pens and 1,000 refills for the Soyuz missions. To this day, American astronauts and Russian cosmonauts use the Fisher Space Pen.

Frequently asked questions

How does the Fisher Space Pen TLP’s telescopic mechanism work?

The mechanism is extremely simple and convenient. You pull the end of the pen and it extends to its normal writing length. Push it back and it retracts to a compact size. There’s no cap to lose. The whole process can be carried out with one hand, making it particularly handy in situations where your other hand is occupied. The length when extended is 12.1 cm, and when retracted, 9.9 cm.

Does the Fisher Space Pen TLP really write underwater and in extreme temperatures?

Yes, this is one of the key features of Fisher Space Pen pens. The SPR4 refill contains a pressurised nitrogen gas cartridge that pushes the hermetically sealed ink. This allows writing at temperatures ranging from -34°C to +120°C, underwater, in zero gravity and at any angle. The pen won’t freeze in winter or run in summer – you can rely on it in all conditions.

What is thixotropic ink and why is it better than ordinary ink?

Thixotropic ink is a specially developed formula which is solid in its normal state but liquefies when writing, under the influence of pressure and movement. This means that the ink doesn’t leak or drip, even when the pen is held upside down. It is hermetically sealed within the cartridge and does not dry out. It lasts up to three times longer than ordinary ink – a significant difference with heavy use.

Is the Fisher Space Pen TLP suitable as a gift for a man?

Absolutely. The Fisher Space Pen TLP comes in a gift box and is ready to give without any additional wrapping. The pen combines practicality, history and unique technology – three qualities that make it an excellent conversation starter. It is suitable for men and women in a variety of professions – doctors, lawyers, military personnel, police officers, teachers, business leaders and school leavers.

What refills does the Fisher Space Pen TLP use?

The pen comes with an SPR4 refill – black ink with a medium line width. In addition, it is compatible with all Fisher Space Pen PR refills. When the refill runs out, you can easily replace it with a new one from the same range. This makes it a long-term investment rather than a single-use item.

What is the history of the Fisher Space Pen and why is it so famous?
