INK SAMPLE - Platinum Carbon Black
A 2ml sample of Platinum Carbon Black fountain pen ink, in a labeled plastic vial. This is slightly different than conventional fountain pen ink, because it is pigmented instead of dye-based. This makes it very permanent and lightfast, though it does require more diligent maintenance in your fountain pen. It's ideal for brush pens and fountain pens being used on paper where you need ink to dry on the surface instead of soaking in.
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.
