These are three of my boxes showing the difference in packaging. I don't know how well it shows in the second pic but the barcode is identical on all three boxes. It is possible that razorbladeclub had old stock, not that that's a problem with razor blades, and I cannot say for definite that they didn't revert to the blue wrappers in the four or five years since I last bought any. I have about 20 years' supply of Personna blades that I bought when I heard they were selling the US factory, so I've not needed any for a while.Chris i got lab blue & med pred all in blue wrappers last year from razorbladeclub
perhaps they have old stock
@Mike M CT I have had the odd Personna Super / lab blue that felt "off", which I never had with the med preps, but it's rare and I rate them highly. The Personna Platinum Chrome, which I've never seen in the box you have, are also excellent blades. They used to be made in Israel and then production was moved to Germany, both iterations are excellent with the German ones possibly being even better than the Israelis.
