Derwent Academy Sketching Pencils have a 6.9mm hexagonal graphite gray barrel.
The thickness of the graphite pencil core depends on its hardness; 2.2 mm for the harder graphite (2B - 5H) and 2.8 mm for the softer graphite (3B - 6B).
The pencils are made of wood and the graphite is of high quality.
They are easy to sharpen and break resistant.
The hexagonal holder makes the pencil easy to hold and use, especially for detailed drawings.
The hardness of the graphite point is printed on the end of the pencil.
