How long are you supposed to keep the box just in case?
Keeping every box until a return window closes can turn a small hallway into packaging storage. Throwing one away immediately can create extra work if the item needs to go back. Instructions sometimes mention original packaging without explaining which parts matter or whether another suitable box is acceptable. What would make return requirements clearer at the time of delivery? We are looking at practical communication and storage, including what belongs on a simple instruction card, rather than guessing the terms of a particular seller.
