Does the ultra-thin mirror have four screws?
Screw it to the end. According to the usage of the slim mirror, the four screws of the slim mirror are used to fix the mirror, which needs to be screwed clockwise from bottom to top, so that the mirror will be more firm and will not loosen. A mirror is a smooth surface. At first, the ancients used polished bronze as a mirror, which had the ability to reflect light.
