NITRAM Mignonettes are Extra Soft (B+) Charcoal Sticks for dark notes & shading. The charcoal itself is dark & velvety smooth. The Mignonettes are approximately 4 mm squares & are 15 cm long (3/16” square x 6” Long). These charcoal sticks can be sharpened to a very sharp point using the NITRAM Sharpening Bloc or Sandpaper. They are low dust as compared to vine & willow charcoal and are easy to erase / blend.
