These classic, hexagonal colored pencils feature vivid, pigment-rich, thick cores for superior coloring and blending. A special bonding process makes Faber-Castell Classic Color Pencil cores super break-resistant and easy to sharpen. The set of 36 pencils is housed in a sturdy metal box. The set of 48 also includes a PVC-free eraser, two Faber-Castell Grip graphite pencils, and a pencil sharpener, housed in a sturdy metal box with removable trays. The pencil barrels are FSC-certified, made from wood sourced from well-managed forests.
