Reflective optical surface applicable to matchboxes, essentially characterized in that it comprises the arrangement of a laminar plane provided on its outer surface with a rectangular and parallel series of profiles of angular section, of vertices that create a multi combination that by transparency of the material and different projection determine changing visibility and interior surface effect to be altered the rational position of the matchbox on which this reflective surface has been applied, obtaining different chromatic combinations.
