Example aspects of a box and a collapsible box are disclosed. The box can comprise comprising a plurality of side panels comprising a first side panel and a second side panel opposite the first side panel; a first top panel extending from the first side panel, the first top panel comprising a primary sealing flap, a first secondary sealing flap, and a second secondary sealing flap; and a second top panel extending from the second side panel, the box configurable in a first closed configuration, wherein the first and second secondary sealing flaps are secured to the second top panel, and a second closed configuration, wherein the primary sealing flap is secured to the second top panel.

A container that is configured to have an open state and a closed state, in which the container includes an outer cell having a plurality of side panels including a first side panel and a second side panel. The outer cell defines a chamber having a first opening. An inner locking member is attached to an inner wall of the first side panel. An extension panel is coupled to the second side panel. The extension panel includes a first cover panel and a tuck flap, in which the tuck flap includes an extension member and a tuck flap locking member. In the closed state of the container, the first cover panel covers the first opening, and the extension member and the tuck flap locking member are tucked inside the chamber. A bias member biases the tuck flap locking member toward a first position to cause the tuck flap locking member to engage the inner locking member.

A method of opening a box includes providing the box in a closed configuration, the box comprising a first top panel attached to a second top panel, the first top panel comprising a first sealing flap, a second sealing flap, and a middle flap disposed therebetween; removing a first tear strip of the first sealing flap to detach the first sealing flap from the second top panel; and removing a second tear strip of the second sealing flap to detach the second sealing flap from the second top panel and to configure the box in an open configuration.

Example aspects of a method of using a box are disclosed. The box can comprise a primary sealing flap comprising a primary adhesive, a secondary flap connected to the primary sealing flap and comprising a secondary adhesive, and a covered top panel opposite the secondary flap. The method can comprise removing a secondary peelable backing from the secondary adhesive; leaving a primary peelable backing adhered to the primary adhesive; and adhering the secondary flap to the covered top panel with the secondary adhesive.
