Herbin is the oldest name in pen inks in the world. "The Jewel of Inks" was created in Paris in 1670. Herbin uses all natural dyes in their fountain pen inks. They are mainly composed of water, humectant to limit drying at the level of the pen and preservative to preserve their qualities over time. This natural composition is reflected in the very neutral pH of the inks. The dyes used have been specially selected to offer the richest color range on the market. Finally these inks are finely filtered so as not to clog the pens. Each pack of Terre de Feu consist of six cartridges neatly and securely packed in a small cylindrical metal tin box. It is a Universal snap-in cartridge which fits most fountain pens and rollerballs, except Sheaffer, Parker, Lamy, A.T. Cross, Pilot/Namiki, Sailor, Platinum, Aurora, Fultz and Nakaya.
