Lock corner, 1 piece box, tuck top, kraft, poly wrapped. Kraft bakery boxes are the economic choice, using 20% less fiber than other box materials. Each one piece box has an attached tuck-in lid, and can be used to hold and carry a variety of baked goods. The lock corners facilitate assembly and enable the box to be folded flat for storage or transport. Recyclable and compostable where facilities exist. Cedar Grove® accepted.
