I checked the blades against the info on the counterfeit website PLUS they will NOT SHAVE MY WHISKERS. All they do is pull them out and THAT HURTS. I have thrown blades away that shaved better than these do new out of the fake packaging. I bought them on Ebay from seller id "mtkozan6" auction #161194169379.
