DAS Wet Strength Cartridge Paper is specially treated to maintain its structural integrity when exposed to moisture, making it a reliable, high-value choice for schools, printmakers, and mixed-media artists. Unlike standard drawing papers that tear or disintegrate when wet, this paper resists buckling, making it suitable for watercolor washes, acrylic painting, ink work, linocut printing, and dry sketching media like graphite and charcoal.
