The Machine Era pen is an ode to the origins of script, updated with modern convenience and class. The brass body offers a satisfying in-hand feel, and a hefty weight that makes you feel like you're writing something important, even if it's only a grocery list. The included Pilot G2 cartridge can be replaced, or switched out to accommodate any standard size Uni-ball cartridge, and the compact construction is perfect for everyday use as you make your way through your writing life.
