Tempered glass mirrors resist breakage and provide a measure of safety from broken glass, but differ in color and reflective quality from standard glass mirrors. Bobrick uses the highest quality tempered glass mirrors. Modest distortion or heat-generated markings are normal in the tempered glass mirror manufacturing process. Therefore, Bobrick will not accept returns of tempered glass mirrors with random distortion or markings.
