Four corner display lid boxes use a top closure style design. A sturdy tray with tall sides holds the product securely. A flap folds up to create a built-in display lid. The lid removes to display products in an open manner. Dual sidewalls add extra strength for heavier items. Pre-glued trays pop open instantly with no assembly tools. The fold-back lid converts into a standing header for retail. Boxes ship flat, reducing storage and shipping costs. Perforation lines let the box form its original shape. Materials include rigid board, corrugated stock, and kraft paper.
