1. A box comprising:

a center panel defining a first side, a second side opposite the first side, a first end, and a second end opposite the first end;

a first locking panel extending from the first side, the first locking panel comprising a pair of wings, each of the wings defining a locking slot;

a second locking panel extending from the second side, the second locking panel comprising a pair of locking tabs, each of the locking tabs engaging a corresponding one of the locking slots;

a first side flap panel extending from the first end; and

a second side flap panel extending from the second end;

wherein each of the first and second side flap panels defines a cut out, and each of the locking tabs engages a corresponding one of the cut outs.

2. The box of claim 1 , wherein:

the first locking panel comprises a first side subpanel attached to the center panel and a first locking subpanel disposed opposite from the center panel and foldable relative to the first side subpanel; and

the second locking panel comprises a second side subpanel attached to the center panel and a second locking subpanel disposed opposite from the center panel and foldable relative to the second side subpanel.

3. The box of claim 2 , wherein the pair of wings extend from the first locking subpanel, and the pair of locking tabs extend from and are hingedly attached to the second locking subpanel.

4. The box of claim 1 , wherein:

each of the first and second side flap panels further defines a side tab; and

each of the side tabs engages a corresponding one of the locking slots.

5. The box of claim 1 , wherein the second locking panel defines a locking notch adjacent to each of the locking tabs.

6. The box of claim 1 , wherein:

the first side flap panel comprises a third side subpanel attached to the center panel and a first flap subpanel disposed opposite from the center panel; and

the second side flap panel comprises a fourth side subpanel attached to the center panel and a second flap subpanel disposed opposite from the center panel.

7. The box of claim 6 , wherein each of the third and fourth side subpanels defines a side tab, each side tab engaging a corresponding one of the locking slots.

8. The box of claim 7 , wherein each of the first and second flap subpanels defines the cut out, each of the cut outs defining one of the side tabs.

9. The box of claim 1 , wherein a plurality of vents are defined through the center panel.

10. The box of claim 1 , wherein the box defines a cavity, a temperature maintaining material received within the cavity.

11. The box of claim 1 , wherein each of the locking slots is substantially aligned with one of the first end or the second end.

12. A modular box assembly comprising:

a box configurable in an expanded configuration and a collapsed configuration, the box defining a box cavity and a box top;

an inner box received in the box cavity, the inner box comprising a center panel, a first locking panel, and a second locking panel, the first locking panel defining a locking slot, the second locking panel comprising a locking tab engaging the locking slot; and

an insulating liner received in the box cavity and surrounding the inner box, wherein the inner box engages the insulating liner, the insulating liner suspends the inner box within the box cavity proximate to the box top, and the box cavity is configured to receive contents between the insulating liner and the inner box.

13. The modular box assembly of claim 12 , wherein the inner box defines a cavity and a temperature maintaining material is received within the cavity of the inner box.

14. The modular box assembly of claim 12 , wherein the insulating liner comprises a first liner and a second liner, each of the first and second liners defining a first liner side panel, a second liner side panel, and a liner center panel extending between the first and second liner side panels.

15. The modular box assembly of claim 12 , wherein the first locking panel defines a wing, the locking slot formed through the wing.

16. The modular box assembly of claim 12 , wherein:

the inner box further comprises a first side flap panel defining a side tab and a side tab cut out;

the side tab engages the locking slot; and

the locking tab engages the side tab cut out.
