Description The Pilot Custom Heritage 912 Black fountain pen with a Soft Fine nib features a glossy black acrylic resin barrel and cap, accented by rhodium-plated trim. The rhodium-plated 14k gold nib is a fan-favorite for its smooth feel on the page. The pen fills with a Pilot proprietary CON-70 push button converter, which holds an ample supply of ink, or you can use Pilot ink cartridges as well. The Pilot Custom Heritage 912 fountain pen comes packaged in a standard Pilot gift box, and both an ink cartridge and a CON-70 push button converter are included to get you started. Please note that Japanese nib sizes tend to run on the finer side, so your line with will be thinner than with a western nib.
