Inktense Pencils by Derwent combine the brilliant intensity of pen and ink with the versatility of precise line and colored wash. This exciting range of water-soluble ink pencils offers a sharp point that is perfect for the detailed work of illustrators, designers, and students. The pencils provide a pure, vibrant color that may be blended and washes out to leave a translucent ink-like effect. Once dry, the color is permanent and may be washed over with other wet or dry media. The Inktense Set of 36 pencils work on both paper and natural fabrics.
