4 years in the making, Pen Type-B is built to last generations! It’s not a space pen or a tactical pen or even feature-rich. It doesn’t even have a clip or a grippy surface. It’s simply the essentials! Precision machined out of solid metal, the body of the pen is made out of stainless steel and the sleeve out of polished brass. A tiny radial pattern of holes near the pen cylinder tip allows for just the right amount of air to flow into the pen to equalize the air pressure on the ink cartridge as you pull the pen out of its sleeve. The ultra-high machining tolerances between the pen and sleeve create a piston-like effect. The pen falls slowly into its sleeve and even makes a pleasant popping sound when you pull it out quickly. Better yet, its brass is purposefully unfinished so it picks up your unique patina over time! Designer:
