Inktense Pencils & Blocks by Derwent
Combining the brilliant intensity of pen and ink with the versatility of line and wash, Inktense can be used for dry rich intense color or washed out with a little water to create a vivid translucent effect. The rich pigment extends further than traditional watercolor pencils, and is more opaque for true ink effect. Once dry Inktense colours are permanent, allowing for artwork to be washed over with other media without bleeding.
