A blank comprising:
- a first end panel defining a first end and a second end distal from the first end;
- a first main panel defining a first end and a second end distal from the first end, the first end of the first main panel joined to and extending from the first end of the first end panel;
- a connecting panel defining a first end and a second end distal from the first end, the first end of the connecting panel joined to and extending from the second end of the first main panel;
- a second main panel defining a first end and a second end distal from the first end, the second end of the second main panel joined to and extending from the second end of the connecting panel;
- a second end panel defining a first end and a second end distal from the first end, the first end of the second end panel joined to and extending from the first end of the second main panel;
- an inside end panel defining a first end and a second end distal from the first end, the first end of the inside end panel joined to and extending from the second end of the second main panel;
- a bending tab joined to and extending from the second main panel;
- and
- a locking tab extending from and separable from the main panel, passable through an opening defined between the second end panel and the inside end panel, and engageable with a locking opening defined in the bending tab;
- the locking tab comprising a first tab subpanel, a second tab subpanel, and a third tab subpanel;
- the first tab subpanel extending from the main panel, the second tab subpanel extending from the first tab subpanel and joined to the first tab subpanel at a first bend line, and the third tab subpanel extending from the second tab subpanel and joined to the second tab subpanel at a second bend line.

A locking device for a box, the locking device comprising:
- a first panel defining a locking tab, the locking tab separable from the first panel and comprising a first tab subpanel, a second tab subpanel, and a third tab subpanel;
- the first tab subpanel extending from the first panel, the second tab subpanel extending from the first tab subpanel, and the third tab subpanel extending from the second tab subpanel, the third tab subpanel of the locking tab configured to bend with respect to the second tab subpanel of the locking tab;
- a second panel defining a locking opening, the locking opening sized to receive and capture the third tab subpanel of the locking tab, the third tab subpanel of the locking tab configured to engage an edge of the locking opening when the second tab subpanel and the third tab subpanel are in facing engagement and thereby configured to prevent movement of the locking tab with respect to the locking opening in an opening direction of the locking device;
- a third panel positioned parallel to and offset towards the outside of the box from at least a portion of the second panel, the third panel and the portion of the second panel receiving the locking tab therebetween;
- and
- a fourth panel positioned parallel to and offset towards the inside of the box from the portion of the second panel, each of the portion of the second panel, the third panel, and the fourth panel defining a front wall of the box, the front wall defining an opening between the third panel and the fourth panel, the opening sized to receive at least a portion of the locking tab therethrough.
