Derwent Lightfast - oil-based coloured pencil

Now with 100 colours available!
Derwent's Lightfast pencils are our first oil-based coloured pencil; formulated to be 100% lightfast (according to the ASTM 6901 standard, rating LFI or II), so the colours won't fade for up to 100 years under museum conditions.
The smooth oil base of the core creates a rich vibrancy and can be mixed on the page to create paint-like effects.
