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. Drop the pen into the sleeve to watch it slide in slowly. Give it a final push so the sleeve can grip the pen and prevent it from slipping back out. Pull the pen 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 pneumatic seal, kind of like a piston.
All of its parts are machined out of solid stainless steel
A balance of simplicity, precision and substance, the pen feels smooth between your fingers
Theres no grip to tell your fingers where to go and its free of notches or grooves
