> was the one who bought it from Birkin

Birkin is not a company/brand, Hermes is the brand that sells these bags.

So no offense to you, but if you don't even know that I'm guessing you're not very up to date on the fashion world in general, and on how authenticity/counterfeit prevention is handled in that space. And your opinion on whether NFTs make that more difficult or easier to handle is probably just an off the cuff guess.
