J Herbin Universal Ink Cartridges are suitable for all fountain pens without a patented cartridge refill. Each pack of seven 'snap in' ink cartridges are presented in a Jacques Herbin signature amber-toned box. Please note, while these cartridges are universal, they are longer than the standard cartridge.
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.
