The Purofino Milenio boxes are engraved: "Purofino Milenio by Alec Bradley."
Yes, they are made in the Kelner plant by the same rollers who roll Davidoff, under contract by Alan Rubin (Alec Bradley.)
And I do find them very similar to the Davidoffs. Certainly, you're not comparing Roger Ralphs' early Purofino lines, Gold, Blue, and Dom to Davidoffs? This is a wholly different line of cigars.
Nor would I compare the Milenio to the Davidoff Millenium. While the construction of both is impeccable, the Millenium was constructed to have a taste profile unlike any other cigar Davidoff has ever made.
