For use with the CW&T PEN SLEEVE Order a Pen Type-B with a custom diamond tip engraving on the flat surface of the pen sleeve. Max 30 characters. Pen Type-B is precision machined out of solid metal. The body of the pen is made out of stainless steel and the sleeve is available in several options: Polished Brass: The brass is purposely uncoated so it picks up your unique patina over time. Titanium: Polished or Matte Black: Brushed with an ultra durable matte black ceramic-polymer coating (Cerakote) The ultra-high machining tolerances between the pen and sleeve create a piston-like effect. The pen falls slowly into its sleeve and makes a nice popping sound when you pull it out quickly. Pen Type-B ships with a 0.3mm Black Hi-Tec-C Ink Cartridge. REFILLS available as well. Made in the USA: Pen Type-B is manufactured at a multi-generation machine shop in Vermont. Each pen is inspected before it goes out, and if there is ever a manufacturing defect we will happily take it back to repair or replace. Refills: To replace the ink cartridge, simply unscrew the back of the pen with a coin. The cartridge in this pen is a Black Pilot Hi-Tec-C 0.3mm cartridge (REFILLS). Hi-Tec-C cartridges are available in 4 line widths and over 30 colors and are widely available in stationery stores in Asia and sold in the USA under the name G-Tec-C.
