NITRAM Baton is a unique charcoal drawing device. It is designed to hold the NITRAM Mignonette, a thin 4 mm square charcoal stick. The Baton has a square, grip barrel which holds the mignonettes securely while drawing. The charcoal advances easily, while keeping the hands clean. The Baton is 20 cm (8”) Long. Each Baton comes with 5 Mignonettes. These 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). NITRAM Charcoal is widely considered to be the finest charcoal for drawing by professional artists, academies & ateliers. They are low dust as compared to vine & willow charcoal and are easy to erase / blend.
