No tools required for assembly. Fold along pre-scored lines to form the box, engage the side flaps, and secure the front tuck closure. Store flat until needed to conserve space. Do not overfill beyond the intended document capacity, as overstuffing may compromise the tuck closure and side flap integrity during transit.
