Nitram Bloc de saule extra soft charcoal

The Bloc de Saule is a large square edged extra soft stick, great for sharp marks as well as covering large areas. Box contains 1 charcoal stick. Can be sharpened to a fine point with the Nitram Sharpening Block. The charcoal allows for deep dark shades while still being easily erased for luminous light effects. If you are working on a piece that requires extra deep black then the Bloc de Saule is more black than the Nitram B. Approximate size: 15cm (L) x 4.6cm (W) x 1.5cm (D). Nitram produces its charcoal using a unique process that maintains the wood's cell structure which increases the charcoal's durability and helps prevent breakage. Nitram charcoal doesn't break like willow or vine do, and feels much less brittle. Also you produce less dust when working expressively.
