Obviousely (and lucky for you) you never met a German postman. Stick labels with "fragile" all over a parcel and you can be sure the sender receives a challenging 2000 parts jigsaw puzzle. Unpoppable bubble wrap is the answer to the prayers of zillions of German senders of snail mail!
(I developed a pretty useful trick, though: I don't write fragile on the parcels but "Beware! Contains syrup" - these parcels usually get handled with great care even by the most brutal mail sorter
)
