Pentalic woodless charcoal pencils are made from superior grade charcoal. The pencils are lacquer coated for clean handling and have a solid weighty feel. Use the woodless charcoal pencil on an angle for broad strokes or with the sharpened point for the fine details. They are great for adding detail to charcoal illustrations. Create highlights with a kneadable eraser. To sharpen, use a regular sharpener, sandpaper block or blade.
