J. Herbin Universal Ink Cartridges - Bleu Nuit
Recommended for medium to broad nibs, Herbin Universal Ink Cartridges are suitable for all fountain pens without a patented cartridge refill.
Bleu Nuit is Herbin's darkest colour after Perle Noir. A blue-blackish shade that tends towards a dark purple, this ink resembles the starry night sky. The ink runs fairly thinly, so can be used without trouble in a broad nib. Each pack of six 'snap in' ink cartridges comes packaged in a cylindrical metal tin.
All Herbin inks are pH neutral and non-toxic. They are water-based and therefore will run if wet. The inks are light fast and only natural dyes are used. High quality paper is recommended for use with Herbin Ink.
