While this pen is compatible with any PR refill, it comes with a Fisher Pressurized PR4 with black ink. That means it can write upside-down, underwater and in zero gravity, just like the one sent to the moon in 1969.
Unlike that pen, however, there are some noteworthy differences this one has that could make it a much more formidable EDC, travel, tactical and adventure-ready writing utensil.

While I can’t say with absolute certainty that this is the brand’s first bolt-action pen, it is definitely the only one in its catalog. That’s a big departure from its other designs, which rely on either caps, a clicker or a twist-activated mechanism. It also makes this pen very fidget-friendly.
The pen is crafted from anodized aluminum, as opposed to the original’s chrome-plated brass. That makes it lighter but still incredibly strong — resistant to corrosion, scratches and impacts.
