It's true. Museum Series Gessobord is the most trusted pre-gessoed wood panel by artists for their work. The superior quality acrylic gesso ground does not dull colors and the lightly sanded surface provides exceptional brush control. This makes Gessobord the perfect art panel for all painting styles with oil paints, acrylics and mixed media. Only Ampersand uses true high-density hardboard made from US grown and renewable Aspen wood fibers. Made with Ampersand's 1/8" True Artist Hardbord, the surface is acid-free and non-yellowing. All 1/8" panels, available in 5x5, 5x7, 6x6, 8x10, 9x12
