Bakery box is made of Kraft paperboard, which is brown on the inside and outside. It has an attached tuck-in lid and a cellophane window to view contents inside. 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 lid tucks into the box to help secure its contents. The lock corners facilitate assembly and enable the box to be folded flat for storage or transport.
