KOH-I-NOOR Gioconda Graphite Lead 5.6mm x 6 6B

Graphite leads in diameter 5.6mm for drawing with clutch pencils. Graphite is a naturally occurring mineral allotrope of the element carbon, and is grey in colour. The key components of these leads are the pure, micro-pulverized natural substances on a base of calcium carbonate. Together with top-quality additives and binding agents, a perfect base mixture is created into which colour pigments are carefully mixed. The pigments are sourced from all over the world and their quality, light permanency and dosed concentration influence the final result as well as the durability of the artworks.
