The rear of the box has an internal order picking label and what is left of a shipping label attached. On the shipping label, a part of the customer number and customer name is still visible (the same name as is written on one of the box sides, which are otherwise blank). The picking label is shown below, and contains numerous codes relating to stock location, order nr, sorting details and who dispatched the order from where. The catalogue number together with the quantity of 1 confirms this box contained one set. What this label sadly doesn't seem to contain is a picking date, which would've been interesting to have.
