Gillette Bleue Extra

No, they're standard blades. The larger box is a natty sort of dispenser where the blades are staggered and you slide out a blade at a time, hence why it's a bit bigger than a cardboard package. You can also use it to dispose of old used blades, there is a special slot for them.
 
I can't speak for the older ones but the new cardboard box Bleue Extras are mediocre IMO. The cardboard box ones can be found in any French supermarket, price about € 1.60 for 10 blades.
