Ok, you have my most sincere apologies if this has already been posted... i'm sure most of us know by now that some ROTF Skids have painted teeth and some don't. now, you can pretty much make the distinction visually through the package, but in case you can't, here are the stamp numbers... Unpainted: 90641 Painted: 90981 and for those unsure of locating the stamp numbers, they're actual indented, not printed, numbers on the lower, right-hand corner of the card back. right below the alt-mode pics. once again, i'm sorry if this has been posted. i searched and couldn't find it. mods, please delete if it is.
