Navy Blue Cerakote Cap-O-Matic Space Pen

The Workhorse, Finished in Navy Blue.

The M4 Cap-O-Matic has earned its place as the workhorse of the Fisher Space Pen lineup. Built for people who depend on their pen every day, its simple one-handed activation and legendary pressurized ink make it a natural choice for the job site, workshop, field, office, and everywhere in between.

Now, the classic M4 takes on a deep Navy Blue Cerakote finish.

Cerakote is a ceramic polymer-based coating engineered for exceptional durability. Its thin, hard finish provides outstanding resistance to abrasion, corrosion, chemicals, and heat, giving the M4 a durable exterior built to stand up to demanding everyday use.

One-Handed. Built to Work.

The Cap-O-Matic's cap makes extending and retracting the writing point simple. Press the flat end of the cap to write, then press again to retract. The one-handed design keeps the M4 ready when your other hand is busy.

From construction crews and first responders to military personnel, tradespeople, outdoor enthusiasts, and anyone who expects their tools to work, the M4 Cap-O-Matic is built for people who don't want to think twice about their pen.

Legendary Fisher Performance

Inside the Navy Blue Cerakote exterior is Fisher's proven pressurized PR-style ink refill. The M4 writes upside down, at any angle, underwater, through grease, and in extreme temperatures from -30°F to +250°F. It writes on almost any surface and lasts up to three times longer than the average ballpoint pen.

The same pressurized ink technology trusted in space makes the M4 a dependable everyday writing tool on Earth.

Classic Design. Durable Finish. Legendary Performance.

The Navy Blue Cerakote M4 Cap-O-Matic combines the proven design of a Fisher workhorse with a tough, distinctive finish built for everyday carry.

Like every Fisher Space Pen, it’s backed by our lifetime guarantee against manufacturing defects.
