A Pack Of 50 x X-Large Single Wall Packing Cardboard Boxes 24x18x18". 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. All stated dimensions are length x width x height.
