Cretacolor Nero Pencil - Extra Soft
Nero produces a shiny black, smudge-proof stroke. It is oil-based and, therefore, water-resistant.
Cretacolor Nero Pencils are excellent for general purpose sketching and drawing when a dense black line is needed. The pencils feature a wood exterior. Using them allows you to avoid all of the mess that is typically associated with oil-based drawings.
