This synthetic paper made of 100% polypropylene offers a unique alternative to traditional art papers. Waterproof and stain-resistant, it is exceptionally strong, durable and will not buckle or tear. It is acid-free, archival and has a smooth, bright white surface. Originally used for offset printing, it also accommodates silkscreen, embossing, pen & ink, drawing, acrylic painting and aqueous techniques. Yupo is machine-made in the USA and recyclable. As a watercolor paper, it has the advantage of being non-absorbent so colors lie on top of its surface producing brilliant, vibrant effects.
