Packaged in a beautiful glass bottle, the limited edition Herbin 1670 Edition Anniversaire Ink commemorates the 340 anniversary of the company, the world's oldest producer of inks. Sealed in gold wax, this new 50ml special edition colour "Emeraude de Chivor" is an elegant emerald green ink with flecks of gold. The 50ml bottle is sealed with Herbin sealing wax and the colour of the wax is a good indication of the ink's colour. It is a fairly thick ink so we recommend giving the bottle a quick swirl before filling. 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 made using only natural dyes. We recommend high quality paper with Herbin Ink.
