The words "Пересылка: НАЗЕМН." (7th line up on the receipt) means "sending by surface".Not deliberately though. Alexander didn't noticed that, as he could not even imagine this could be done to the parcel going across the water to Japan. Also his previous shipments were going 'airmail' just by default.
All this knowledge makes nobody happy, only helps to understand what has happened. And why it takes sooooo long for the parcel to arrive - they give it 8(!) weeks - which means 8th August?
