Created especially for Remai Modern in Mpumalanga, South Africa, this box of charcoal sticks is handmade by Simon Attwood, who has been making William's favourite charcoal for use in his practice for many years. Made from sustainably sourced Sesbania, Erythrina and Mulberry.

"One of the things about charcoal drawing is that it is instantly alterable - you can change it as quickly as you can think. One wipe of a cloth and the image disappears or is smudged and you can rethink it. The flexibility of drawing is important. There's an immediacy of drawing, of thinking in drawing, which is vital for me." - William Kentridge
