After the 1670 classic ink colours of Hematite Red, Blue Ocean, Stormy Grey and Emerald of Chivor, comes the fifth and new 1670 ink colour, Caroube de Chypre, commemorating Herbin's 340th anniversary and his fondness for dried carob pods that he picked up on his way home sailing through the Mediterranean. The colour is a rich and intense deep brown with a hint of red and gold speck - it's truly unique, stunning and special. Packaged in a limited edition gold embossed box, this will be a truly special edition to your fountain pen ink collection. Herbin has been around since the year 1670, hence the name for their premium ink line. The 1670 line launched in 2010 at their 340th anniversary. 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 only natural dyes are used. We recommend high quality paper with Herbin Ink.
