Dating back to a small boutique in Paris in 1700, Herbin Fountain Pen Ink is one of the best in the world, both in smoothness of writing and breadth and brilliance of colour palette. One of Herbin's most boldly pigmented inks, Larmes de Cassis is strong and assured in its purple-ness. This versatile bold ink can be used on ivory or white paper, for professional or personal writing. All Herbin inks are pH neutral and non-toxic. They are water-based and therefore will run if wetted. The inks are light fast and only natural dyes are used. We recommend high quality paper with Herbin Ink.
