Derwent, 2302719, Lightfast, artist's crayons, 12 pcs.

Product detailed description

Lightfast crayons are an absolute novelty in terms of the nature of the lead used, which is a first for Derwent oil-based crayons. 

The lead is 4 mm thick and is housed in naturally treated wood. 

The crayons are guaranteed to be 100% lightfast (the drawing is lightfast for 100 years in museum conditions), the lightfastness was tested in certified laboratories in Arizona. 

The crayons layer very well and blend with other crayon lines.

The shades are intense and experts compare them to Luminance crayons from Caran d'Ache. 

A set of 36 crayons, which had undergone extensive testing to meet strict lightfastness requirements, was available from July 2018. A further 36 shades were tested by the end of 2018 and the beginning of 2019. In July 2019, a further 36 shades were launched, for a final number of 72 colors available, after which the number stabilized at 100.

The crayons are "Vegan friendly". 

You can choose from five set sizes - 12, 24, 36, 72, 100 pcs (launched in July 2019).  If you want to try out how the crayons paint on a smaller sample of pencils, you can choose from 100 pcs of piece crayons. 

The crayons are not water-washable and are supplied in a metal cartridge.
