A cardboard box with an insert is a two-part pack: an outer carton that takes the impact, and a fitted insert inside it that holds the product still. The insert is what actually prevents damage, because most breakage in transit comes from movement rather than from the drop itself. We cut inserts to your product dimensions with a 1 to 2mm tolerance, so items sit snug without forcing. These packs suit fragile goods, multi-piece kits and premium products that need to arrive presented as well as intact.
