- a second main panel connected to the first main panel and facing the first main panel;
- and
- an end panel extending from the second main panel, the end panel defining a locking opening, a lateral width of the locking tab at the ear being greater than a lateral width of the locking opening, a lateral width of the locking tab at the neck being less than the lateral width of the locking opening, the locking opening sized to receive and lockably engage at least a portion of the locking tab upon assembly of the blank into the box;
- wherein the end panel comprises a second end panel, an inside end panel, and a connecting panel joining the inside end panel to the second end panel, an intersection between the connecting panel and each of the inside end panel and the second end panel defining a bend line;
