Derwent Lightfast Pencil - Grass Green

100% Lightfast, 100% control, 100% quality. Derwent Lightfast Pencils have a revolutionary core that is resistant to prolonged colour change, ensuring your artwork will not fade for up to 100 years under museum conditions. The smooth oil base creates rich, vibrant colour and can be mixed on the page to create a lovely paint-like effect - the pigments completely integrate to form new and vibrant colours. The pencils also offer excellent control over layering, and blending is dense and even thanks to the thickness of the core. Ensure your work stands the test of time with these high quality, lightfast pencils. All the Derwent Lightfast pencil range has been tested according to the ASTM D6901 standard, which states that pencils with a rating of LFI and LFII are fully lightfast.
