A bronze midsection gives the pen a solid, weighty feel in the hand, while a carbon-reinforced polymer midsection keeps the pen ultra-lightweight (without sacrificing strength or durability.)

Two Carry Options
The Contrail is available with either a lanyard hole (which allows the pen to be carried loose in the pocket and on a key ring) or an integral pocket clip.
