A Pack Of 25 x X-Large Single Wall Packing Cardboard Boxes 610x457x457mm (24"x18"x18"). Perfect for large size items, and a good size for warehouse/ dispatch use at an economy price. Very popular with cash and carry style stores and online sellers. Is also a popular single wall carton used in lighter removals and moves for light items. We would recommend a combinbation of these and double wall boxes for a house or business move, as single wall boxes should not be used for very heavy or delicate items, and do not stack as well as double wall boxes when stored.
