A real strong, double wall option for those of you packing heavier products. Manufactured using an EB flute, double wall board grade, they enable you to pack and ship your heavier products, without worry. With a label placement mark printed on the one panel and 'no knives' markers on the top flaps, they are great for those more fragile products. We have a one off supply of these unused cartons available and they will not feature online again, once they are gone!
