Grips layer after layer: The sanded tooth holds repeated layers of soft pastel, oil pastel, charcoal, and colored pencil, so color builds rich and vivid without filling in or losing bite. No fixative needed between layers: The abrasive surface locks pigment in place, letting you work and rework color without spraying fixative as you go, for cleaner and truer results. Takes a wet underpainting: Accepts water, alcohol, and solvent washes without buckling or losing tooth, so you can block in an underpainting before moving to dry pastel or pencil. Acid-free and archival: The pH-neutral sheet resists yellowing over time, protecting finished pastel, charcoal, and mixed media work for years of display or storage. Consistent professional surface: Even, end-to-end grit coverage gives predictable results across the whole sheet, from bold underpainting to fine detail work.
