Drawing Inks have been used by illustrators since their introduction by Winsor & Newton in the 1890s, where the main requirement is brilliance of colour. Today they are formulated from a series of soluble dyes in a superior shellac solution. These inks can be applied with brush, dip pen or airbrush and are widely used by designers, calligraphers and artists as well as illustrators. Good, old-fashioned drawing ink from iconic little bottles. Fast-drying, water resistant and transparent. All the colours are intermixable and you can overlay different colours for new effects and shades.
