Platinum Chou Kuro - 60mL Bottle



Platinum Chou Kuro fountain pen ink is the blackest ink ever created from Platinum in its 104-year history!

Caution: Pigmented inks are intended for use in fountain pens, though they require more diligent maintenance and should not be left to dry out in a pen. It is best to clean it from your pen at least once a week to prevent clogging. Certain pens may handle pigmented inks better than others.
