Herbin inks are water based, non toxic and pH neutral. The ink flows smoothly and is fast drying. All ink colours in the Herbin line are made with natural dyes.
The 30 ml ink bottle has an integrated pen rest which is an unique feature specific to the Herbin ink bottle. Herbin 30 ml ink is often referred to as the “D” bottle pen inks. The “D” refers to the old French unit of measure “la Demi Courtine”.
Eclat de Saphir (Sapphire Blue) ink colour is based on the sapphire gemstone. The terminology probably comes from 2 origins: the Greek with “sappheiros” (a stone of blue color) or from the Hebrew “sappir” (the most beautiful thing). This colour is a reminder of Herbin and his work at the most prestigious royal courts of Europe.
