Herbin's calligraphy and specialty inks include rich metallics, shimmering pearlescents, and inks steeped in history. These inks are not for fountain pens. They are best suited for steel nibs, glass or quill pens, calames and brushes.Pigmented ink is exquisitely rich and opaque with a high pigment content. A decorative ink, it delivers very dramatic on dark-coloured paper and is best suited for wide nibs, brushes and calames.*Gold and silver inks contain actual metallic pigments (shake bottle vigorously and frequently while using).
