Violette pensée (Pensive violet): this color is also a flower from the very same name. Since Napoleon I, French pupils used violet ink color, the least expensive color. This ink was made of methyl-violet, also used to disinfect wounds.
J. Herbin is the oldest name in pen inks in the world. M. Herbin created “The Jewel of Inks" in his shop on the Rue des Fosses Saint-Germain in Paris in 1700.
Herbin uses all natural dyes in their fountain pen inks. This natural composition is reflected in the very neutral pH of the inks. Each bottle of 30 ml/1 oz ink is elegantly labeled and has a pen rest. They are known as “D bottle pen inks." The “D" refers to the old French unit of measure “la Demi Courtine."
