Larmes de cassis (Tears of blackcurrant): this ink with a dark purple hue is the symbol of grievance and penitence (Tears).

Herbin is the oldest name in pen inks in the world. "The Jewel of Inks" was created 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.
