What is right with the pencil lead, is also highly welcome and functional for a coloured lead. The well-known technique ensures that the point of the crayon always has the same length regardless of the lead’s wearing.

The history of the renowned pencil manufacturer Koh-i-Noor dates back to the 18th century. Throughout the world, Koh-i-Noor became known through the innovative invention of Joseph Hardtmuth, who in 1792 developed a novel method for pressing and baking pencil leads - mines did not have to be cut from the solid stone any longer. This innovative ability has been preserved at Koh-i-Noor to this day.
