Derwent Onyx Pencil, 4mm Core, Pack, 6 Count (2300039)
Derwent Onyx Pencils produce dark, rich, dense tones with the consistency between a charcoal pencil and 9B. Lines are darker and more black than regular graphite with no gray tone, so they're as close to being charcoal black as you can get, with the comfort and convenience of a pencil. Set includes Onyx, Medium x 2 and Dark x 2, a pencil sharpener and an eraser.
