Charcoal pencil with vintage design The Soft Carbon pencils are very similar to the traditional charcoal pencils, yet their special composition makes them very soft. The stroke smoothness and the influences of Viarco’s historical material are the way to the Vintage design selected for this product. Soft Carbon is both a good drawing tool and a great way to convey the entire Viarco tradition. Available in set of 6 pencils or box of 48 pencils (8 x 6).
