Pack of 5 - Heavy Duty Medium Cardboard Packing Boxes

These heavy duty medium cardboard packing boxes are ideal for moving house or storing heavier items that need extra protection. Sold as a pack of 5, they are double-walled for superior strength and rigidity compared to standard single-wall boxes, making them well suited to books, kitchenware, tools, and other dense or weighty contents.

Manufactured in the UK by StorePak from recycled cardboard, each box measures 405 x 405 x 405mm — the same cube format as our standard medium box but with significantly more robust construction. Strong enough to stack safely even when fully loaded.
