Unlike paper, Pastelbord offers a rigid substrate with a sandy clay coating that is more durable and versatile. The granular marble dust finish provides a fine grain tooth that holds layers of pastel and other dry media like no other surface. This museum-quality ground is acid-free, pH neutral, and non-yellowing for true and lasting colors. Layer, blend, and dust to create rich and luscious colors. Use this sturdy hardboard with both dry and water-based media including soft pastels, oil pastels, pastel pencils, charcoal, colored pencils, watercolors, ink, and acrylics. Available in gray or white.
