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. Rose Tendresse is a very romantic pink colour. Though very bright, it retains its body on white or ivory paper alike. The perfect ink for writing love letters! 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.
