Caran d'Ache is a brand specializing in the highest quality articles for artists. One of their iconic products are the Luminance 6901 pencils. Luminance pencils, thanks to their creamy consistency, are perfect both for applying them to larger surfaces and for working with details. They have maximum light resistance, in accordance with the ASTM D-6901 standard, which classifies artistic crayons in terms of photosensitivity. This ensures an excellent durability of up to 100 years. The binder of the graphite of Luminance 6901 crayons is wax. The crayons superimpose themselves perfectly, which allows you to blend colors, create smooth transitions and shading. Luminance 6901 are made of cedar wood, thanks to which they sharpen very well and the wood does not crumble. They are considered the softest art pencils by many artists. We would agree that they are on the podium, but in their buttery consistency they remain balanced, thanks to which they do not pose any difficulties when we “switch” from harder crayons, such as Faber-Castell Polychromos. They are softer than most crayons on the market, although they fall behind Prismacolor Premier and Winsor & Newton Studio Collection crayons The entire range of colors consists of 100 vivid, pure and opaque colors, which at PaperConcept you can buy online through our shop, as well as in stationary stores in Warsaw, Gdańsk, Kraków, Katowice, Poznań and Wrocław.
