A box is made by folding a sheet of material. Preferably, the box is formed by applying adhesive and folding using a machine, and a waterproof or water-resistant coating is applied to the sheet of material so that the box is configured for use as a cooler. The box includes: a storage portion, including a bottom panel, first and second end panels, and first and second side panels; four corner panels; and first and second top panels. The top panels include openings that register when the box is assembled and in a closed configuration to define an opening to be used as a handhold for gripping the box. Reinforcing panels of one of the top panels includes flaps located on an interior of the box that cover the handhold opening. The box further preferably includes a locking tab and locking panel for latching closed the top panels of the box.
