A box is collapsible in such a manner that it can form a flat stack of panels, each of which corresponds to one side of the box. When the box is configured as a flat stack of panels, it is relatively compact and, therefore, easy to store. When the collapsible box is configured as a box, it is sturdy and strong. The collapsible box has latching elements that can temporarily connect adjacent sides of the box to one another. Typically, a person can latch and unlatch the latching elements with his or her hand. The box is typically transparent and, therefore, well suited for displaying ornamental items, such as ornate hats.
