What goes wrong
Store the six sizes as six locations, not one crash-lock pile.
Packaging Boxes lists Crash lock boxes for this line. Ecommerce lines that fit a listed size can live on crash lock. Other lines should not be forced onto it.
The check before you reorder
Pick from the six sizes. If none is close, use single wall rather than a crash lock that is mostly air.
Store the six sizes as six locations, not one crash-lock pile.
Dispatch on that order
A Packaging Boxes basket with Crash lock boxes still leaves the same day if it is placed by 3pm. The terms aim for 5.30pm the next working day. A 1 to 3 day courier is also described, depending on the lines.
