All-purpose, 100 lb., acid-free paper has slightly more texture than Strathmore's best-selling 80lb. 400 Series Drawing Pads. 400 Series Heavyweight Drawing is recommended for use with pencil, colored pencil, charcoal, or sketching sticks to achieve a greater depth of tone, uniform areas of half tone, and less mechanical renderings in cross hatching. Twenty-four sheets per spiral-bound pad.
