A shipping and display case having a unique series of perforated tears and cuts for opening the case. The case may have a conventional box shape, including front, back, left, right, top and bottom panels, and the case is provided with a perforated tear line that is used to open the case. The score line is formed by a multitude of perforations or slits; and the slits in selected portions of the tear line are substantially longer than the slits in the rest of the tear line. In particular, in the portions of the tear line that cross over left and right front edges of the case, and in selected angled portions of the tear line, the slits are substantially longer than the slits in the rest of the tear line. These longer slits make it easier to cut or tear through areas where it is normally difficult to tear cleanly.
