The Derwent Inktense Blocks have all the brilliance of the Derwent Inktense Pencils but in a solid block, making it easy to cover large areas really quickly. Just like the pencils you can use the blocks dry but they come into their own when you mix them with water?and the colour turns into vibrant ink. Once dry the colour is permanent and you can work over the top of it. Also ideal for using on silk and cotton!
