S.T. Dupont Royal Blue is a well-behaved blue ink with moderate shading that fades from a rich color when wet to a vintage, faded appearance when dry. It features great fluidity and is easy to clean from pens, making it suitable for everyday writing on most paper types, though its low water resistance makes it unsuitable for archival purposes.
