What goes wrong
Crash lock does not replace an Amazon carton. Those follow the FBA or Amazon Shipping maximums on that category.
Packaging Boxes lists Crash lock boxes for this line. Order the crash lock size with any extra tape you still want on the other seams. The strip covers its own seam.
The check before you reorder
The category describes the board as 150K/T, recyclable and biodegradable, and sized towards Royal Mail small parcel guidelines. It lists six sizes.
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.
