Description
The vivid colours are specially formulated to combat the effects of UVA radiation, 100% lightfast and guaranteed to last 100 years under museum conditions, it complies with both the ASTM D-6901 and Blue Wool Scale ISO 105. Strict testing for international lightfast standards is done in Arizona, US.
A note about lightfastness, this does not equate permanence, as other factors can affect the permanence of work such as humidity, temperature, atmospheric pollution, the reaction between chemicals and pigments, the paper being used, etc.
Being ideal for works on permanent display, it is perfect for professional artists as well as hobbyists who exhibit their work. Colour names and numbers are embossed in blue on each pencil for easy identification. The Easy-to-grip round barrels feel good in your hand and will fit standard pencil sharpeners.

I completely fell in love with these pencils and the best news is that the 72 set will be released soon. The lightfast goes on so creamy you almost get the idea that it could be a crayon but in pencil form. They cover the area very quickly and with little preasure you have this dark rich colors. I think these pencils will work well for people that hands get tired soon and you need min. preassure and the pigment is there. They hold their point well and I haven’t had any breakage so far. The lightfast obviously plays in the artist favour with keeping that pigment for a 100 years under museum conditions. A realy great pencil that I can definately recommend.

I haven’t had the time to test the lightfastness of these pencils, but if the manufacturer says it’s serious about lightfastness it’s usually better than nothing. (Always do your own lightfastness tests! Manufacturers, no matter how good, always lie a little!) The feeling of these pencils are really such that it reminds me more of a normal wax crayon. If Faber-Castell was the “ideal” colour pencil (which is not at all like a crayon) and Prismacolor was the lovely soft powdery form of this, then these pencils definitely are in another category. If you dislike crayons, look elsewhere. If you like even coverage, opaqueness, and a relatively strong point – go for these.
