Faber-Castell PITT Pastel Pencils are part of a unique color matching system that encompasses all Faber-Castell Art & Graphic products. Each pencil contains the highest quality pigments for unsurpassed light-fastness. Buttery smooth color lay-down provides excellent color opacity and can be blended for layered effects, highlights and transitions. Extra-thick 4.3mm leads can be wiped like ordinary pastels. Gentle fixing is recommended. Each pencil is housed in California cedar wood casing with SV (secure-all) bonding to strengthen lead and prevent breakage, while providing sharp fine lines and excellent point retention.
