This edition of the M4 features the new Cerakote colorways. Our signature topo pattern is laser applied to reveal the brass body below in contrast with the Cerakote.

Fisher Space Pens are renowned for their ability to perform in adverse conditions. The technology starts with a non-skip, textured tungsten-carbide ball encased in a stainless steel ball socket. The sealed ink cartridge is pressured at about 45 psi and contains a visco-elastic, thixotropic, solid-gel ink. Able to write upside down, under water, in extreme temperatures and in zero gravity, Fisher Space Pens are ultra-reliable tools to aid in analog data storage and communication.

A great everyday writing utensil, the Cap-O-Matic is a click pen that provides you with the expert feel you’ve come to expect from Fisher Space Pens..

The TAD edition is laser engraved with our logo and signature topo pattern, laser etched below the Cerakote to reveal the brass body. We worked hard with Fisher to ensure the quality of the engraving. The resulting pen is a classic form factor with a Triple Aught Design edge.
