Sorry, I should have been more clear, and this is widely out there on the internet so it is no secret to Counterfeiters. There is no "LONGCHAMP TYPE" on the first line on the back of the lable, it just says "LONGCHAMP"
On the 2nd line it will say LE PLIAGE SHOPPING if it is a longer handled bag (small, medium, or large). If it is a short handled bag (4 inches) the 2nd line will say LE PLIAGE TYPE "S" if it is a small, or LE PLIAGE TYPE "M" if medium, and will have an "L" if large (with the quotes around the S, M, or L. If it says "TYPE" but does not have the corresponding size, then I that is also said to be fake. I just checked my bags that unzipp in the middle around the bag to make them bigger; all the mediums and larges say LONGCHAMP on the first line and LE PLIAGE "EXTENSIBLE" on the second line. These bags are really awesome if you travel a lot for business as I do. And, they all say "Made in France" on the inside label, and coincidentally, these bags seem to be stronger and better made. I don't think it's my imagination either, they are holding up better on the corners and other wear.
Also, if that ebay seller says "Longchamp TYPE or Longchamp Inspired" in the title of their listing or in the body of their description, they know they are selling a fake, and I suspect this is a way of refuting if someone files a grievance with ebay or asks for their money back. They can point to the fact that this was clear in the listing. I sent one of them an email saying their bag was a fake and she replied it was why she mentions "Longchamp Type" in the listing. Amazing.
Hope that helps!
