J Herbin Invisible Ink 30ml

J Herbin is the oldest name in pen inks in the world and goes right back to a small boutique on the Rue des Fosses Saint-Germain in Paris in the year 1700. We consider J Herbin Inks to perhaps be the best in the world, both in smoothness of writing and breadth and brilliance of colour pallette.

The ink turns blue when held under a light or other heat source. Writing disappears as the paper cools. Looks pink in the bottle but writes clear! A fun way to send meaningful correspondence and really produce a memorable letter!

All J Herbin Inks are pH neutral and non-toxic. They are water-based and therefore will run if wetted. The inks are light fast and and only natural dyes are used. We recommend high quality paper with J Herbin Ink.
