The identity of dark matter - the mysterious stuff that makes up about 22% of the Universe’s energy contents - continues to elude scientists decades after they first inferred its existence. That's what makes Dark Matter exciting: It's still one of the great mysteries of science. Just as the observance of Dark Matter through gravitational lensing helps us detect its very presence in our universe, it also helps illustrate the eye-popping and mesmerizing titanium finish gleaming from this pen. The Dark Matter Black Titanium Bullet Space Pen provides the ultimate sleek, stealthy, high-end pen capable of withstanding the elements while maintaining a professional standard of style.

Conceived in 1948 by Paul C. Fisher, the Bullet has been a part of pop culture over the past half a century. Seen on the Tonight Show with Johnny Carson and being the focus of the Seinfeld episode entitled ‘The Pen’, this highly sought-after space pen keeps customers coming back, from generation to generation.

When closed, the Bullet is the perfect size to carry in your wallet, pocket, purse, car glove box, organizer, or toolbox. When open, it’s a full-sized, evenly-balanced writing instrument that performs in the most unique environments. Like all Fisher Space Pens, this pen will write in zero-gravity, upside down, underwater, over oil and grease, in -30 to +250 degrees Fahrenheit, and three times longer than the average pen. Whether you’re a trade professional, writer, teacher, artist, executive, or just someone who appreciates a premium writing experience, at an affordable price, this space pen is for you. Fisher Space Pens were developed to be the best all-weather pens on the market.

The Bullet design is timeless and elegant, yet extremely durable, something most ballpoint pens are not known for. When someone says, “I’ve got a space pen.”, most of the time they are referencing the Bullet. Again, further evidence of its popularity and solidifying its place in history as a “classic” in the ballpoint pen industry.

On January 6, 2022, what was once known as the Black Titanium Nitride Bullet Space Pen, officially became DARK MATTER. The perfect name was chosen from a community campaign to give this pen an appropriate space-age title. Before Dark Matter, naming creations conceived by the Fisher Space Pen community included Purple Haze, Aurora Borealis Green, Pink Nebula, Red Planet and Blue Moon. Special thanks to our loyal fans for helping us rename this space pen.
