The ones in the red packaging were affectionately called Israeli Reds having been made in a factory in Nazareth Israel.
The one in the red, white and blue package were made in that same plant for sale in the UK. Everyone I have read seems to think they are the same as the Israeli Reds.
You might still be able to find some of the Israeli blades, but as inventory becomes scarce, the prices have risen.
A couple of years ago, Edgewell announced the closure of the factory in Israel and production was moved to Solingen, Germany. This is the same plant that also produced the Wilkinson Sword Classic blades. Edgewell owns the Personna, Schick and Wilkinson Sword brands with the exception of some regions where Gillette owns the Wilkinson Sword brand. The Personna Platinums in the blue and gold packaging are made in Germany.
I have only tried one tuck of the German Personnas as I still have about 90 Israeli Reds. As far as I could tell, the blades were the same as the ones made in Israel. However, I have also read reports indicating that the German blades are inferior in quality. Thus, I do not know if the German blades are the same as the Israeli ones. Even if you order blades that are advertised as Israeli Personnas, you might end up with blades made in Germany. I think the term "Israeli Personna" is being used by some as a generic description just as "Kleenex" and "Scotch Tape" have come into common language to describe facial tissue and clear adhesive tape.
