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. A regal colour, Eclat de Saphir is a wonderfully iridescent, classic blue ink that is perfect for professional use. With its rich, bold colour, it also happens to be NoteMaker's favourite blue! 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.
