Colorama is the most popular background with professional photographers around the world. It's made of high-quality paper and installed on a cardboard core which allows you to easily mount it on a background holder. A great benefit of a paper background is that if it gets dirty, you can just cut it off – length of 11 meters allows you to use the background for years without it getting too short.
Paper backgrounds are perfect for studio use, for designing a scene, etc.
