From seller : The Esplendido a purchased from a Habano Sommelier in Havana. They regularly get boxes and samples from the factories and Habanos SA. That box is 100% from the El Laguito factory, which is the mother factory of the Cohiba brand. The factory code of the El Laguito was MAR, now it is GES. It is hard to say when they changed it, because it does not happen from one day to another. With the code of 000050791106, I agree with you. This barcode was used on 2021 boxes. Maybe they stamped the box later, and that is why the inconsistency between the date stamp and the barcode. I sent you many photos, when I offered the box to you. I did not want to hide any detail. What you can be sure, that the box is from a reliable source, and the content of the box is 100% authentic Cohiba Esplendidos cigars. This box is over 2500 USD in Havana in the shops, and over 3000 in Europe. I could give it to you for 1800 because I could buy it from a Habanos Sommelier, who would never sell non factory cigars.
He is willing to arrange for a refund.
