Nooooobody knows... or at least I don't know - some other brands come with a similar card too. For a while you could buy them in bulk on iOffer, because replica sellers thought that was the critical thing to put in their auctions.
i think it's the small paper card with the numbers from 1 to 9.
b bags come with this, with the paper with the name and year on it, and the logo.
yup - I get that - but what is it's purpose for existing?
I have no idea. Since they're not actually an identifier of any kind, I've always thought they were a little silly. I mean, it's not like the numbers are circled or checked in some kind of code!
When I next to go BalNY, I will ask. Maybe we'll learn some deep, dark Balenciaga secret!
How about the notches on the Lampo zippers -- what do those mean, LP?
