Derwent-Inktense Pencils. Pure, vibrant water-soluble ink pencils that combine the intensity of pen and ink with the versatility of line and wash. Use them to create strong vivid tones then wash over with water for a translucent ink-like effect. Once dry, this color wash is permanent and can be worked again using other media. Great for using on fabric such as silk and cotton. The possibilities are endless! This package contains twelve Inktense pencils: Sun Yellow, Tangerine, Poppy Red, Fuchsia, Deep Indigo, Sea Blue, Teal Green, Apple Green, Leaf Green, Baked Earth, Bark and Ink Black.
