63L Heavy Duty Cardboard Box | 5mm Kraft Brown | 700L x 300W x 300H (mm) | The Box Man

The Medium Heavy Duty Shipping Box (SHIP-7.3.3) is made for businesses shipping long, narrow items that need a sturdy rectangular format. Whether you’re packing tools, sporting equipment, or elongated industrial parts, this heavy-duty box delivers 63 litres of usable volume, a narrow 300 × 300mm profile, and the length needed for items that don’t suit standard box shapes.

LONG AND NARROW, BUILT TO SHIP

Not everything fits a square box. The Medium Heavy Duty Shipping Box (SHIP-7.3.3) gives you 700mm of length in a compact 300 × 300mm cross-section — ideal for long, narrow items that would rattle around inside a wider carton. Built from 5mm double-wall Kraft cardboard for reliable crush resistance without the bulk and weight of a 7mm board where it’s not needed.

STRONG, SUSTAINABLE, AND MADE TO LAST

Made from premium Kraft corrugated cardboard, manufactured in Australia using 100% Australian paper. Our paper is sourced from a blend of recycled materials and sustainably managed forestry. Contact us to check suitability for very heavy or sharp items.
