About This Product
Platinum Carbon Ink is the pioneering permanent ink for fountain pens. This deep black ink is made with extremely fine carbon black pigment, and once it's dry, it's not going anywhere. Soak your paper in water; scrub it with a brush; layer a bunch of paint on it. Carbon Ink won't lift or bleed into your colors. It won't smudge under your eraser, and it's completely lightfast.
Better yet, unlike other permanent inks, Carbon Ink is safe for fountain pens. Because of its small particle size, it flows almost as freely as a standard dye ink and won't damage your pen. (We do recommend regular pen flushes when using pigment ink, though, just to keep things running smoothly.)
Four cartridges per box. This proprietary cartridge format only works with Platinum and Kuretake fountain pens. For other pens, try Platinum Carbon Ink in a 60 mL bottle.
Made in Japan.
