Fisher Space Bullet Pen

The Zero-Gravity Icon.

The Fisher Space Pen Bullet is arguably the most famous pen in the world, and for good reason. Originally developed for NASA astronauts, this American-made marvel is engineered to perform in environments where ordinary pens fail. Whether you are in freezing cold, scorching heat, underwater, or just trying to write on a greasy receipt at a job site, the pressurized ink cartridge delivers a smooth, skip-free line every single time. With its timeless mid-century design, the Bullet Pen folds down to a compact size that disappears in your pocket, then expands to a full-sized, balanced writing instrument when you are ready to work.

Key Features

• Write-Anywhere Reliability: The patented pressurized ink system allows this pen to write in zero gravity, underwater, over grease, upside down, and in extreme temperatures ranging from -30°F to 250°F.

• Iconic Bullet Design: Recognized by the Museum of Modern Art as an example of classic industrial design, the brass body features a sleek bullet shape that is perfectly balanced and incredibly durable.

• Compact & Portable: When closed, it is small enough to fit in a wallet, coin pocket, or travel kit. When the cap is posted on the end, it becomes a comfortable, full-sized pen.

• Tactical Matte Finish: Features a durable matte black finish with chrome accents, providing a professional, low-profile look that resists scratches and reduces glare.

Why We Love It

The Bullet Space Pen is the definition of "buy it for life." It is one of the few pieces of gear that is truly over-engineered for daily life. We love that you never have to worry if it will work—you just pull it out and write. The "thwack" of the cap sliding on is satisfying, and the way it transforms from a tiny capsule into a full-length pen feels like magic every time. It’s a piece of space history you can carry in your pocket for under $30.
