Sketching pencils set with 12 degrees of hardness features hexagonal, easy-grip barrels that helps you keep a comfortable grip for accurate laydown. Its easy-to-sharpen, break-resistant graphite helps to stop it from snapping under pressure to prevent wasteful use. Each degree is printed on the end of every barrel for easy identification. For smudging, the dark, smooth, soft B pencil is your best choice. For fine, straight lines, choose a hard pencil that will hold its point. Metal tin keeps all 12 pencils neatly organized and secure.
