Twin Lock #2 from LBP Manufacturing is the ideal size for mac and cheese, a quarter chicken meal with mashed potatoes or a full Mexican meal with burrito, rice and beans. Perfect for white table restaurants and upscale caterers seeking a clean, simple design. Patent-pending, twin-locking system closes easily and ensures a secure closure. Comparable to popular preformed to go boxes, but with the addition of push-to-open vents.
