The Mountaineer Clutch Space Pen from Fisher comes in a matt black finish and is a big chunky pen weighing in at 33g compared to the familiar bullet Space Pen. The pen comes with an integral pocket clip and is retractable using the push button mechanism.

Manufactured in Nevada, USA, this pen is produced to exacting standards and utilises Fisher's tungsten carbide ballpoint and patented visco-elastic ink in a pressurised cartridge. As a result, the Fisher Space Pen can write in the most demanding environments:

• In the zero gravity vacuum of space
• In extreme heat up to 200°C
• In extreme cold to -20°C
• Underwater
• Upside down
• On grease

This pen is fitted with an SPR4 black medium point refill.
