Really? Photo albums, toys not made of wood, footwear, typewriter ribbons, clocks, bells? What on earth are they trying to prevent happening in Italy? Wouldn't want people having access to clocks now. Or maybe this has to do with some sort of trade war of which we had previously not been aware, but if that's the case, how odd that it applies to things that are being mailed versus importers of large quantities. I can't imagine that it would be cost efficient to be mailing shoes to the Italians one pair at a time through the post office.
It's very strange.
