They are particularly suitable for professional users like artists, designers, architects and graphic designers. The new voluminous graphite tip offers a wide variety of line widths with grades of hardness that provide many different tones of grey. The Castell 9000 is a genuinely classic pencil, launched by Count Alexander von Faber-Castell in 1905. Its quality and finely graduated degrees of hardness have made it a firm favourite with artists and illustrators. Its lead is fully bonded with the wood surround and is therefore particularly break-resistant. It's available in 16 different degrees of hardness, from a delicate grey hue to a deep graphite black, making it ideal for all technical and artistic applications. The high quality Castell 9000 Jumbo pencil features extra thick graphite lead. It is perfectly suited for quick sketches and drafts as well as shading extended areas and artistic work. Each pencil has an environmentally safe water-based coating and is extra break resistant.
