Wondernaut has done several excellent reviews of the new Herbin 1798 Cornaline d’Egypte ink and most of the new Herbin Jewel of Inks. Click on the links below to see the reviews!
This one’s missing the title but it’s Bleu des Profondeurs
The only one of the 5 new Jewel of Inks not reviewed is Rouge Grenat, maybe that review is coming soon?
