If it is extra strength you are looking for, then this once used, strong double wall box might be an option for you. Manufactured using a double wall board grade, these are great for packing heavy or valuable items. Perfect for use as a removals box too! We have a regular supply of these once used cardboard boxes but unfortunately we do not get many at a time. If you like saving the planet whilst packing your products, then continue buying used boxes instead of new boxes and help save the environment whilst reducing your packaging costs! These have been used for import into the UK and the appearance on the images above/adjacent, reflect the condition you will receive them in.
