Key benefits Polycarbonate mirror with refractive index and low density provides bright, clear reflections with good light transmission. Not easy to deform; hardness; environmentally friendly and nonpolluting. The mirror naturally rebounds to its original shape after external pressure is removed; concave deformation disappears. Humanized hat design effectively covers rain and sun, giving pedestrians and drivers a clear view. Gift accessories include screws and nuts for installation. Specifications and features Material: PC (polycarbonate) mirror offering good light transmission and durability. Performance: hardness, stable shape, and environmental friendliness.
