Jacques Herbin's Vert Cactus is a mesmerizing green-brown (darker than olive) fountain pen ink that hits a balanced, earthy perfection. It reads as either a brownish dark-green or a greenish brown, just like you'd expect from something named "Cactus Green." Like all of Herbin's regular fountain pen inks, it is pH-neutral and therefore safe in all kinds of vintage fountain pens, including latex sac fillers (i.e. most vintage lever-filling pens) and celluloid-body pens.
