Pen Type-A is an homage to our favourite writing utensil, the Hi-Tec-C. We’ve been using this pen in its plastic housing for years, until we decided that these coveted cartridges deserved a more durable home.
The sleeve doubles as a straight edge and a measuring instrument. Its edges are clean and sharp, lasting evidence of the precise machining processes that were crucial to its construction.
Pen Type-A is held pneumatically inside its protective case. Drop the pen into the sleeve to watch it slide in slowly. Flip it up-side-down to slide the pen out or pull it out quickly and hear a light popping sound.
These effects are a result of high tolerances between the pen and the sleeve that create a vacuum like a pneumatic piston.
