Observe the clarity. When choosing the protective film, be sure to observe its clarity. Whether the color of the film is dark or light, you must check whether its outer contour is clear enough. Some inferior floors may appear foggy, and may even cause the outer contours of objects to be deformed. If the quality floors are dark or light, the clarity is quite high. Check the scratch. The floor film is used to protect the floor, so you must check the anti-scratch performance of this floor film. The high-grade and high-quality floor film is not only not easy to be scratched, but the most important thing is that it can be better. Protect the floor.
