CASTELL 9000, a genuinely classic pencil, was launched by Count Alexander von in 1905. Premium quality and finely graduated degrees of hardness have made it a firm favorite with artists and illustrators. Its lead is fully bonded with the wood surround and is therefore particularly break-resistant. Ideal pencil for all technical, artistic applications and writing.
