Tsukineko All Purpose Ink, sold per .5 ounce bottle (see our non-metallic colors too). Due to its blendability, washability and versatility, quick-drying Tsukineko All Purpose Inks have become a favorite among fabric artists. And because it’s water-based and non-toxic, All-Purpose Ink is fun for artists of all ages. Use it on wood, paper, leather and other porous surfaces too. All-Purpose Ink must be heat set on fabric for permanence. Heat set between color applications to prevent bleeding.
