Fake Serial Number For Mount And Blade How Do I Know If Cologne Is Real, Fake, Or Just Stolen?

How do I know if cologne is real, fake, or just stolen? - fake serial number for mount and blade

There is a flea market near my home town of Cologne and distribution. I wanted to try and Dolce & Gabbana and many have. I have a bottle of $ 20. Did I say my parents and told them they are wrong. However, the packaging and the bottle looks really. It smells great too!

Is there a way to know whether the colony is true or false? Serial number or something. I have not seen a good number on the bottle.
