Recently I wanted to mail someone in Italy a t-shirt and a couple of postcards, but I found out that they are prohibited! I don't know if this big list of prohibited items signals increasing problems with the U.S. mail or problems with the Italian customs office or both. Either way, it's not looking good. Also, one must fill out all U.S.P.S. customs forms at home on a computer (including the weight of package and phone number of recipient) and print it out before taking it to the post office. NO MORE hand-written forms!
