As pen creator CW&T puts it, this pen is "over-engineered to crazy town," utilizing precision, pneumatics, and stainless steel. It is an homage to Pilot's Hi-Tec-C pens, which the CW&T designers regard as awesome and deserving of a durable body that can be passed down from generation to generation. Manufactured at a family-run machine shop in Vermont, the pen has a smooth weighty stainless steel body and perfectly houses a Hi-Tec-C ink refill. The pen is stored in a stainless steel sleeve, and when fitted together, the pen and sleeve are like a piston, creating a pneumatic seal that protects the pen. In addition, a rubber ring inside the sleeve protects the pen tip and prevents air from entering the tip. Pulling the pen out of the sleeve breaks the pneumatic seal, generating a fun "pop" sound. The sleeve functions beyond carrying the pen---it's a ruler, with centimeters and inches marked on one side, and a handy straightedge for drawing.
The pen comes with a Pilot Hi-Tec-C 0.3 mm black ink refill, and accepts any Pilot Hi-Tec-C refills.
Pen dimensions: 4.8 inches length, 0.4 inches diameter (12.3 cm length, 9.8 mm diameter); sleeve dimensions: 0.5 x 0.5 x 4.7 inches (1.2 x 1.2 x 12.0 cm).
