These are some of the strongest boxes we have available currently. Produced in two board grades, exactly the same size. You will not be disappointed with either type, they are incredibly strong and well capable of carrying heavyweight or valuable items. If you are in the market for a low cost, incredibly strong box, that is not too big and easy to carry, then these are perfect for you. They are available on a one off basis only and once they are gone, they will not show online again. Order a pallet today to try out, they really are of the highest quality!
