Product Description
This edition of the 400 Bullet 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.
When you think of Fisher Space Pens, the original model 400 Bullet is what first comes to mind. This pen is known for its small portable size, brass casing and unique form factor. Small enough to carry in your wallet, pocket or toolbox, the Bullet becomes a full sized, evenly balanced writing device when opened.
The TAD edition is laser engraved with our logo and signature topo pattern, revealing the brass body below the Cerakote. 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.
