Hi. I'm having a little bit of difficulty navigating this forum, so my apologies if this information is posted elsewhere. I recently purchased this Michael Kors large Selma in black off of Ebay. Everything seems authentic based on everything I've found online and based on comparison with my other MK bags (zippers, logos, stitching, hardware, country/model number/color code tag...), except for this interior heat stamp. None of my many other MK bags have this and I haven't found any bags online that have this. Also, the bag arrived with an odd, very strong chemical smell. Thanks.
