It would be a tragedy to dissect a real cohiba but at least you would know that you have 24 good ones left. If you cut it up and it is junk, you have not smoked junk. If you cut one open you should see whole leaves with the hard veins cut out. If you find shredded tobacco you have a fake. If you find one fake they are all fakes.
People want to believe they got a good deal but fakes are probably more common than real cohibas.
Also, you don’t want to smoke fakes, they could be banana leaves or who knows what! Obviously there is no quality control in fakes because the sellers don’t care about repeat business. Once a Cuban criminal sells you a box of fakes, they don’t want you to find them again.
Check the box. There is a fake cohiba box page link at the bottom of that link I posted above.
