The Pilot Custom Heritage 92 has a semi-transparent barrel which reveals the mechanism of the piston, the coil and the black stopper which seals in the ink in a completely airtight manner. It uses a rotating suction mechanism (piston-fill) with ink capacity of 1.2mL. The clear barrel allows the user to see not only the remaining ink, but the colour of the ink as well. It also comes in a gift box.
