Frequently asked questions

What can I pack in a 9 x 6 x 6 inch double-wall cardboard box?

This size is suited to small dense goods, hardware and protected electronics when the packed contents fit comfortably. Use dividers, wrapping or void fill according to the item.

Why choose this box for compact double-wall postal orders?

Its dimensions and double-wall construction provide a practical balance of capacity and rigidity for this use. Pack heavier items low and prevent movement inside the carton.

It can be reused while it remains dry, rigid and free from tears, crushed corners or weakened seams. Inspect the base carefully before repacking it.

Should empty space be left inside this cardboard box?

Leave only the space needed for protective material and safe closure. Fill unwanted gaps so the contents cannot shift, but do not overpack the box or force the flaps shut.
