In cube-corner retroreflective sheeting 3, cube-corner retroreflective elements in at least two mutually adjacent regions A and B rotate with each other around an axis perpendicular to the sheeting, in which cube-corner retroreflective elements 11 and 12 not in contact with boundaries between the regions A and B are cube-corner retroreflective elements having a hexagonal shape, and cube-corner retroreflective elements 11s, 12s, 11t and 12t in contact with the boundaries between the regions A and B are cube-corner retroreflective elements having a shape obtained by cutting parts of one or two reflective lateral surfaces of the cube-corner retroreflective element having a hexagonal shape where the partly cut reflective lateral surfaces are in contact with the boundaries.
