^(To Bagsnbags) Nope, it's the same as the Mono canvas. Good damier fakes are usually lighter in color and appear more matte and as Jazzybelle said, stiffer than the authentic one. Also, the lower grade ones look pretty waxy in appearance and darker in color.
This is the waxy type:
However, the REALLLY good ones from Korea (We're talking really scary good fakes here) are usually be defined thru scrutiny of the interior and hardware. The color intensity of the fake damiers are also on par with the auth ones.
Also, the checkbox with the LOUIS VUITTON usually appear not more than twice on small leather goods (Wallets, pochette cles) and once on others like the Ludlow.
What I know of the damier papillon is that there is alway a centered LOUIS VUITTON check in the middle of the side canvas. And 4 on the body? These are the observations I've had thru what me and friends have of our own damier pieces.
