Winsor & Newton Drawing Inks have been used by illustrators since their introduction in the 1890's, where the main requirement is brilliance of color. 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. These brilliant colors are fully intermixable and they are easily diluted (with distilled water). Fast drying and water resistant, they have excellent adhesion on most surfaces. This William Collection Ink Pack contains eight 14 ml bottles. Colors include: Black (Indian Ink), Brilliant Green, Deep Red, Peat Brown, Purple, Sunshine Yellow, Ultramarine and Vermilion.
