Strathmore 400 Series Heavyweight Drawing has been one of their most popular papers since 1940. Previously, this 100 lb (163 g/m) cream colored paper was only available in sheets and rolls. Now Strathmore has introduced 5 convenient pad formats to the Heavyweight Drawing family of prodcuts.All Heavyweight Drawing products feature a medium surface with slightly more texture than the 80 lb. 400 Series Drawing pads. This allows for greater depth of tone, uniform areas of half tones and less mechanical looking cross hatching. It is also durable enough to stand up to repeated erasing and reworking. Excellent for use with pencil, colored pencil, charcoal, or sketching sticks.Available in wire bound pads of 24 sheets.
