The PITT Oil Base pencil range from Faber-Castell features the classic monochromatic tones found in almost every art school classroom. Available in several degrees of hardness in both black & sanguine tones, they harken back to traditional figure drawing dating back to the Renaissance. Ideal for contours, outlines & fine details, they're harder than a conventional pastel pencil, offering a smudge-proof application & water-resistant finish.
