Tom Norton Walnut Ink is a beautiful brown ink that combines modern conservation features with the look and feel of traditional walnut ink. It handles like watercolor, lifting easily and making gorgeous washes when diluted with water. It flows well from either a dip pen or a brush, so both calligraphers and painters can experiment with it. Finally, unlike traditional walnut ink, the rich color of Tom Norton ink won't fade, and its acid-free composition won't damage your paper over time. We carry two sizes and the darkening fluid, which deepens the color to a near-black. Made in the United States.
