Like the guide I have just read, I too got taken with a package of 40 of these "Asian" blades, which also tore my face, and were absolutely useless. The 4 blade packages (total 10) that I received ,all had an elongated hang up slot at the top, with a hole in the middle. The ones for sale legally in all U.S. outlets only appear to have just one small, round hole at the top of each package. I was lucky,...I got my money back ,and the seller ,after I told him the facts ,didn't even want the phony blades returned. Just look at the blades being offered for sale, and look for the clues I have pointed out. Contact the seller before purchase and ask are the blades manufactured in the U.S.A. If he refuses to tell you, then he too is a phony. Hope this is of some help to other prospective buyers of Gillette blades.
