The raw brass composition of our M4RAW is made of 85% Copper and 15% Zinc, making this pen a copper alloy that possesses antimicrobial properties, which were registered by the EPA in 2008.  The clip and tip of the M4RAW Cap-O-Matic though are made of steel, while the body of the pen is raw brass.  If you’re like us, you value any type of PPE that can be useful during today’s uncertain times.  Fisher Space Pen is proud to bring to you an antimicrobial pen to help lessen the health risks we are faced with while providing support to Feeding America’s mission, making sure families have the ability to keep enough food on their tables.

At Fisher Space Pen, we note several models of pens that we consider to be the “backbone” of our business.  While the AG7, Bullet and Shuttle Series pens have always been the stars of the stories, the classic Cap-O-Matic Space Pen has truly been the blue-collar, workhorse of the bunch.  Single hand activation makes this model the pen of choice for construction crews, law enforcement, firefighters, military, first responders, medical professionals, outdoorsman and women and anyone who demands dependability in their writing instruments.  The creation of the Cap-O-Matic allowed Fisher Space Pen to offer the same technology used by astronauts, in a single hand activation but at a price that everyone can afford!

Containing a Fisher Space Pen® Pressurized Ink Refill Cartridge, the #M4RAW will write upside down - at any angle, under water, through grease, in extreme temperatures (-30 to +250 degrees F), on almost any surface, three times longer than the average pen, in the gravity free vacuum of space, and each is guaranteed for quality against all manufacturing defects.
