A fine introduction into the world of high-end Japanese fountain pens, the Custom Heritage 92 features an exquisite 14k gold nib, striking design, and—rare among Japanese fountain pens—a built-in piston filling system. The pen holds 1.2 ml of bottled ink, which is twice as much as a typical converter-filled pen can hold. The transparent demonstrator body design nicely shows off the pen's inner workings.

To use the piston filler, turn the knob at the end of the barrel counter-clockwise to extend the piston, submerge the nib in your ink bottle, then screw the knob tight to retract the piston, drawing ink into the pen straight from the bottle. Be careful, operating the piston while ink is in the pen will cause ink to leak out of the pen.
