I find that the new set is not exactly the same as the ones I had been using. Everything is the same, except, on the new set, the smallest drills are on the left, size increasing to the right. Old sets had smallest on right, size increasing to left.
Also, the clear sliding cover now fits into detents in the blue base. I suppose it could still be same supplier who updated the package, or it could be new supplier that just copied the package. Neither old nor new sets have any marking on them, though the new one came in a blister package with trademark with letters SE on it. But since I do not have packages any more from my old sets that doesn't mean anything to me. The drills do work, that is all that matters, really.
