@onlyk and I think if you keep your original proof of receipt of purchase from LV, then if you go to re sell it that should be fine, along with the LV store can always authenticate it, especially if you have a good relationship with your LV SA. If anyone else has any thoughts on this, please share them with us in here.
Re the LV denim KP I think the inside lining or stitching being smaller is the main feedback I am getting from some of the other people who have reached out to me, and bought one. Maybe there is only a slight difference, say in that mine can fit a few credit cards, albeit very snugly versus the worst case I heard, being one poor lady told me she couldn't even fit one credit card inside, she said it wouldn't zip up apparently, so she returned it. But after seeing my video she said she was going in store to LV to look at them in real life and see if she could fit her cards in those ones. TBH I am slightly perplexed by it all, especially seeing how easily (my over two decades old OG) mono key pouch fits in the credit cards, pretty effortlessly as you can see in my video. Maybe it's my own naivety that I assumed the Key Pouches would all be uniformed in size, even over the years.
Overall I still love mine and am keeping it, and just hope my video might help anyone else who is thinking of grabbing one. If anyone else has a story to share regarding all of this, please do let us know in here.
