Platinum Carbon Black is a water-resistant fountain pen ink that is pigment-based. It's a top black ink that is both popular and well-reviewed. Carbon Black is water-resistant thanks to its use of pigments as opposed to dye to create the color. In addition to being water-resistant the ink is also heat-resistant and fade-resistant.
