Fisher Space Pen – Model 400GGCL Lacquered Brass Bullet

Fisher Space Pen is the brand whose pens have been flying in space since 1967. The 400GGCL model is the first and most popular in the 400 series – compact, elegant and crafted from lacquered brass.

The lacquer preserves the metal’s original colour and prevents tarnish. For those who prefer natural brass with its antibacterial properties and patina, there is the 400RAW model.

Reliability in extreme conditions

Every pen is precision-assembled and hand-tested before leaving the factory. It comes with a lifetime guarantee against manufacturing defects.

Writes reliably at:

Temperatures ranging from -34°C to +120°C
Underwater and in other liquids
In zero gravity
At any angle, including with the tip pointing upwards

How the refill works

The SPR4 refill contains a pressurised nitrogen gas cartridge. A small metal cylinder pushes the special thixotropic ink, which is solid when at rest but liquefies when writing.

The result is a pen that doesn’t leak, doesn’t skip and writes up to three times longer than standard ink. The tip is made of tungsten carbide.

The Fisher Space Pen 400GGCL is a suitable, prestigious gift for men and women in various professions – doctors, lawyers, military personnel, police officers, business leaders, teachers and school leavers.

It doesn’t leak in the heat or freeze in the cold – reliable both in the car and in your everyday bag.

The history of the Fisher Space Pen

In the early NASA missions, astronauts wrote with pencils. In 1965, Paul S. Fisher of Fisher Pen Co. designed a pen capable of functioning in the unique environment of space – in zero gravity, underwater and at extreme temperatures.

The company invested around 1 million US dollars of its own funds, without any funding from NASA. 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 dollars each.

In February 1969, the Soviet Union also ordered 100 Fisher pens and 1,000 refills for the Soyuz spacecraft. To this day, both American astronauts and Russian cosmonauts use Fisher Space Pens in orbit.

Frequently Asked Questions

What is the difference between the 400GGCL model and the 400RAW model?

The 400GGCL model is made of brass and coated with a lacquer that preserves the metal’s original colour and prevents the formation of a patina. The 400RAW model is made of untreated brass – over time, it develops a natural patina and possesses antibacterial properties. The choice depends on personal preference – a shiny, lasting finish or a vibrant, naturally ageing metal.

Can the Fisher Space Pen 400GGCL write underwater and at low temperatures?

Yes. The SPR4 cartridge uses pressurised nitrogen to force the special thixotropic ink towards the nib. This allows writing underwater, in other liquids, at temperatures ranging from -34°C to +120°C, in zero gravity and at any angle. The pen does not freeze in winter or run in summer.

How long does the Fisher Space Pen 400GGCL refill last?

The SPR4 refill writes up to three times longer than standard ink. The ink is hermetically sealed and does not dry out, even during prolonged storage. The pen does not skip or leak, which further extends the cartridge’s actual lifespan.

Which refills is the Fisher Space Pen 400GGCL compatible with?

The pen works with all Fisher Space Pen PR refills. The set includes an SPR4 refill with black ink and a medium line width. Once it runs out, you can fit any other PR refill from the Fisher range – options are available in different ink colours and line widths.
