Derwent XL Charcoal Blocks

Charcoal just got bigger and more beautiful! These blocks have all the qualities of charcoal that you love in a chunky XL form, combine that with rich natural colours and you've got an artist's dream!
The blocks come in 6 muted shades from Sanguine and Violet to Sepia and Ochre. Naturally water-soluble you can use them on a damp surface and release lots of colour really quickly and build up layers of different colours as you go.
