My point is that the puzzle should be updated to inform the reader that designing the right kind of box is a part of the puzzle:
"Jan and Maria each have plenty of padlocks, but none to which the other has a key. Using only the padlocks, keys, and a custom-designed box, how can Jan get the ring safely into Maria’s hands?"
