Derwent Inktense Pencils

Derwent Inktense are a watercolour pencil that intensifies in colour when water is added. Derwent have tried to reproduce the strong vivid colours of ink in the form of a pencil. Once the pencil work dries the colour is fixed and permanent. They can be used on paper, canvas, ceramic, wood, fabric and many other porous surfaces. For more info visit the Derwent website.
