ABSTRACT:
A round trip mailer box is formed from a unitary corrugated cardboard blank with a plurality of scored lines for a quick and easy folding of panels to set up the box. The corners of the box are reinforced and strengthened by folding and bracing corner panels. The folding of the box is completed by inserting tabs on two interchangeable and overlapping top panels, one over the other, into cutouts on opposite sides of the box. These overlapping top panels can be interchanged so that when a mailing label is placed on each top panel, the box can be mailed to a recipient and later remailed back to the sender by simply interchanging the relative positions of the top panels. The box is easily secured in its closed position by taping or other closure means at the two inserted end tabs of the box and is easily opened, reclosed and reused.
