Derwent Lightfast Coloured Pencils are a 100% oil-based pencil. This product was created after much research and development, and provides pencil artists with a lightfast drawing and colouring tool with a smooth texture. The pencils' core is thick and gives dense colour application, resulting in the most vibrant colour. Their smooth and creamy texture allows for effortless colour laydown, and they can even be used with oil mediums like turpentine to give a painterly effect when dissolved.
The revolutionary colour core of these pencils is manufactured from ingredients that resist colour change, so your work will remain as bright as ever and will not fade for up to 100 years under museum conditions. All colours comply with international lightfast testing standard, ASTM D-6901, and tested in Arizona, US.
