Cretacolor - Nero Stick
Water and smudge resistant.
The Cretacolor Nero Sticks are oil-based charcoal pencils that produce permanent, deep black lines. These versatile sticks are water and smudge resistant, and they are more difficult to break than graphite sticks. Nero Sticks work excellently in conjunction with traditional charcoal and all water-based media. Available in three softness grades.
