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.

Because of its solid strength, the charcoal can be sharpened to a fine point with the Nitram Sharpening Bloc . Also you produce less dust when working expressively. The charcoal allows for deep dark shades while still being easily erased for luminous light effects.

The Demi Bâton de Saule are two extra soft rounds, ideal for artists working expressively or large. If you are working on a piece that requires extra deep black then the Bâton de Saule is more black than the Nitram B .

Box contains 2 round charcoal sticks.

The charcoal is approximately 152 mm long and 25mm wide.
