Replacement Pencil Blades for SharpDraw Pencil

Package of three replacement pencil blades for our SharpDraw pencil. The blade-like leads are carbon-fiber reinforced to make them fracture resistant. They mark a consistent 1mm thick line at about the darkness of a standard HB pencil. The replacement blades are also compatible with most 9mm utility knives, making it easy to convert an existing knife into a precision marking pencil.
