I wrote a little about J Herbin inks when I reviewed vert olive in November 2018.  The ink today Poussière de Lune was bought simply because its purple and I liked it when I came across it on the Fountainfeder website.  I had not seen it before and yet now when I look I discover it one of the most popular inks around and has been so for about 10 years. It is also a good alternative for those that like Scabiosa from Rohrer and Klingner and are worried about IG inks in their pens

I think everyone that owns a fountain pen will own at least one J Herbin ink – I may be wrong but at least everyone must have heard of them.  I resisted these inks for sometime as they are everywhere and I could never find a colour I wanted to try but then I got lured in by the shimmer inks.  
J Herbin is the oldest name in pen inks, the original Herbin was a sailor who brought recipes for inks and sealing waxes back to France from his travels around the world.  New inks are still produced – six in 2018, a new shimmer ink (Cornaline d’Egypte) and 5 ordinary inks (Rouge Grenat, Bleu Des Profondeurs.  Bleu Calanque, Corail des Tropiques and Vert de Gris).
