I really wanted to say, "straight from the fake factory," but that would have been wrong...
On another note, please, before posting, save both yourselves and the authenticators some time.
Look at past posts in the forum. Time and time again, your questions might already be answered! For instance, "The Bagmaster" is known to sell nothing but fakes, so if you ask, it might not be answered. Simply put, if you have to ask from there, it's fake, but just don't buy it in the first place.
Also, regarding Neos, for what must be the tenth time now, there has never been a color called "mustard." Half of the colors these counterfeiters are spitting out never existed! A rainbow of pink shades were never in the line; go back to my list and see. Neos (and nylon Le Pliage bags, for that matter) DO NOT come with dustbags. There's a 99.99% chance it's fake if it has one. Only if the seller has a bunch of bags and has a bunch of dustbags around, like I do, would maybe in a world where pigs fly would an authentic one of these have a dustbag. But I would still never do anything like including one to make someone question the authenticity of something I was selling at the time.
So please, follow the rules, and when you don't get an answer, there's probably a reason.
Thanks!
