Winsor & Newton Calligraphy inks are made from high quality pigments in acrylic. We understand the calligraphy is a noble, old-art form and we were determined to do it justice - the 18 colours in this range are lightfast for long lasting results. Our calligraphy inks are not water-proof, which means they can be reactivated with water. For best results use with a brush or a dip pen.
