Recommended for medium to broad nibs, Herbin Universal Ink Cartridges are suitable for all fountain pens without a patented cartridge refill.
Gris Nuage captures the essence of a cloudy sky at sea, when it slightly darkens just before a storm. It is a fairly light grey and tends more towards blue-black than pure black. 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.
