Mixed Media Archival Canvas Board is a 100% Cotton artist canvas which combines the texture of a natural, woven fabric with a specially formulated gesso designed for all water-based paints. It will not tear like paper and you can lightly lift out pigment or completely wash out your painting surface without damaging the canvas surface. The 260gsm (7.7 oz.) double-primed canvas features an acid-free absorbent based titanium gesso for professional results. A versatile option for watercolors, watercolor crayons, acrylics, inks, spray paints, paint and permanent markers.
