The Derwent Inktense blocks combine the colours of the Inktense pencils with the freedom that comed with using colour blocks, making it easier to cover large areas in a small amount of time. With the small addition of water, these blocks can be used to create a deep and intense, watercolour like wash. Once the wash has dried, you can work over the top of them. Sets come in tins of 12 and 24.
