Prismacolor Colored Pencils are the most popular colored pencils we sell. Each colored pencil features a thick, soft core made from brilliant, light-resistant pigments, to ensure smooth, rich laydown and color saturation.The colors are easily blended, slow to wear, break-resistant, and waterproof. Each 3.8 mm core is enclosed in a round cedar casing that is lacquered to match the core.Manual sharpening is recommended for these pencils. Clogging can be prevented in electric sharpeners by periodically sharpening a graphite pencil to keep the blades clean.
