This substantial 8-1/2'' by 11'' sketchbook is ideal for larger drawings and studio projects. The professional quality, 128 gsm sketch paper should not be confused with lighter paper found in most sketchbooks. The heavyweight fine-tooth paper is perfect for dry media, including pencil, charcoal, Conte crayon, and chalk pastel. All pages are micro-perforated for easy removal with clean edges (192 pages/96 sheets). The sturdy book binding lies flat for ease of use. The archival-quality paper will keep your artwork pristine for years to come.
