  • The Pump Piston filler is a high capacity filling mechanism that is powered by a piston unit activated along a piston rod. The rod attaches to the piston unit via three spokes easily and freely. Once the piston rod is secure in the J-lock on the piston unit, the piston unit can be detached from the piston connector at the back of the pen by turning the piston knob counter-clockwise and be pushed towards the section, which expels the air in the barrel.

  • We recommend the use of dye based fountain pen inks only. Use of pigmented inks or iron gall inks may leave visible residue inside the clear barrel that cannot be removed.

    Please place your pens on a pen tray or a pen rest when not in use at a desk. While the materials used in the Kyuseido Kakari and the Kyuseido Kosumi lines are of the highest quality, vertical impact may cause damage to the pen. Repairs are possible but will carry a repair fee.

    Please do NOT attempt to self-repair. Always contact your Authorized Retailer first if you are having issues with your Pump Piston Filler.
