Pelikan Drawing Ink is suitable for engineering, graphic and fine art applications on paper and board. Colors are opaque, lightfast and reproducible. Waterproof when dry.
My introduction to Pelikan Ink happened when I was stationed in Germany in 1960, and I have been using it ever since. Before that time and since on occasion I have used other inks, but in my opinion Pelikan Drawing Ink is the best drawing ink available, period.
