Yupo is a unique alternative to traditional watercolor papers. It is an incredibly durable, stain-resistant, non-absorbent synthetic paper that holds ink with razor sharp precision. Tree free, this 100% polypropylene machine made paper is acid free and archival. With a smooth, briht white surface, colors retain their true clarity and brilliance. Yupo requires no soaking, stretching or taping flat. Color can be lifted completely off, while paper resists tearing and buckling. Yupo is an extremely forgiving sheet. Yupo is also ideal for offset printing, silkscreen, embossing, drawing, pen & ink, acrylic and more. Made in the USA.
