Try Carbon Ink!

Platinum Carbon Ink is a unique fountain pen ink that is completely waterproof when dry. Try using it for linework that will be colored with water-based media, for dark, permanent marks that you can rely on. Use Carbon Ink cartridges with Platinum pens like Preppy, Prefounte, and Procyon. Use bottled Carbon Ink with any brand that accepts a converter or fills with an eyedropper or piston system. Check out our list of suggestions for your new fountain pen & watercolor sketching kit.
