Derwent Sketching Graphite Pencil Tin of 6 Drawing Pens The rollerball takes standard inkSketching should be a loose and simple artform. That's why Derwent Sketching pencils are available in three simple grades, HB, 2B and 4B. These pencils have a wide 4mm graphite core allowing you to quickly rough out a sketch before sharpening the point to add the fine details. This tin of 6 pencils contains 2 of each lead grade as well and a basic pencil sharpener.
