Description
The Fisher Space Pen PR Series refill is designed to write where ordinary pens fail. The SPR1B model, with a line width of 1.3 mm, lasts three times longer than standard refills.
Each refill provides over 3,600 meters of writing, depending on the surface and how it is used. This makes it an exceptionally economical and reliable solution for everyday use.
Why the Fisher Space Pen PR Refill Is Different
The key is in the design. The ball is made of tungsten carbide—one of the hardest materials used in pens. It ensures a smooth, even line under any conditions.
The ink is thixotropic and is stored in a hermetically sealed, pressurized container. An internal separator keeps it separate from the pressurized nitrogen, ensuring a constant flow without leakage or drying out.

Frequently Asked Questions
How long does the Fisher Space Pen SPR1B refill last?
The Fisher Space Pen SPR1B refill provides over 3,600 meters of writing. The exact lifespan depends on the type of surface and writing style. It lasts three times longer than a standard ballpoint pen refill. The ink has an expected lifespan of over 100 years, even when not in use.
Can the Fisher Space Pen write underwater and at low temperatures?
Yes. The pen is designed to write underwater, at any angle, including upside down. It operates at temperatures ranging from -35°C to +121°C, making it suitable for use in extreme outdoor conditions. The pressurized thixotropic ink ensures a consistent flow regardless of the conditions.
For which chemicals is the SPR1B cartridge suitable?
The Fisher Space Pen SPR1B refill fits all Fisher Space Pen pens, with the exception of the Q4 model. The set includes a white adapter that extends the refill by 2.5 cm. Thanks to the adapter, it can also be used in Parker pens and similar models with the same format.
What is thixotropic ink, and why is it important?
Thixotropic ink is a special type of ink that has a thicker consistency when at rest and does not leak. When the ball moves, it softens and is applied smoothly to the surface. This technology prevents leakage and drying out even during prolonged storage. The ink is hermetically sealed in a pressurized reservoir, separated from the nitrogen by an internal separator.
What are the dimensions of the Fisher Space Pen SPR1B refill?
The length of the refill itself is 8.9 cm. The included white adapter adds another 2.5 cm, allowing it to be fitted into longer pens such as Parker. The line width is 1.3 mm, which classifies it as a bold-style pen. The ink color is blue.
What is the cartridge ball made of, and why is it important?
The ball is made of tungsten carbide—a material with exceptional hardness and wear resistance. This ensures smooth and consistent writing on various surfaces, including rough or damp ones. The hard tip is key to reliable performance in all weather conditions.
Is the Fisher Space Pen SPR1B a good gift for a man?
The Fisher Space Pen SPR1B refill is a practical, high-quality accessory, perfect as a gift for a man who appreciates durable and reliable tools. It comes in a blister pack, ready to give as a gift.
