How much w does the electric background axis of the studio change?

The background of Mazui Studio is divided into paper background and canvas. The size of the canvas is calculated according to your wall. If you don't need to ask about the size and price, the paper background is usually around 100. The length of the background axis is 3 meters, but the length can also be customized. The price is between 200 and 300, which is also very cheap. But the paper is not only polished, but also has a poor texture.
