24"x 25'rolls are priced per roll. ROSCOLUX is the most widely used color filter range in the world. The premier range from Rosco, a leading producer and innovator of color filter products, Roscolux employs a unique technology to ensure the longest possible life under hot theatrical lights. In a tri-extrusion process, three discrete layers are combined, with the colored layer sealed between two microscopically thin layers of clear film. This minimizes dye migration and extends the effective life of the filter. Also available in 20"x24" sheets.
