The Southern Champion Tray 24133 bakery box is made of Kraft paperboard, which is brown on the inside and outside, has an attached top and a cellophane window to view the box's contents, and can be used to hold and carry baked goods. Paperboard is thicker and more rigid than paper, is suitable for holding baked goods, and can be recycled - just be sure to remove the window film before placing in the bin. The attached top flips open to insert or remove baked goods. A hinged back enables the box to open completely and lay flat on a table or counter. When closed, the top fully overlaps the bottom. The box has a four-corner beers design with four glued corners for sturdiness. Diagonal scores allow the box to be folded flat for storage or transport. The box measures 9 x 9 x 2-1/2 inches (L x W x H), which is the perfect size for pies and other baked goods.
