Derwent Inktense Pencils are as versatile as watercolor pencils, but with a firmer texture that allows them to perform with the brilliant intensity of traditional pen and ink. These pencils are available in strong, vibrant colors which work beautifully on their own or can be mixed together to create rich, subtle tones. The pure, clean colors are perfect for bold expressive drawings, including fashion illustration, landscapes, greeting cards, and more. Inktense pencils can be used dry for rich, intense color or washed out with a little water to create a vivid translucent effect. Once dry, the color is permanent and can be worked over with other media. Pencils are pre sharpened.
