Louis Vuitton small leather goods/wallets VERNIS guide
This will be simple and sweet, when purchasing anything on eBay and it is a VERNIS line, please make sure you feel the inside of the leather good. IT MUST BE CALFSKIN, so it must feel as though you are touching a soft powdery surface to be authentic. You can be fooled by other things but the calfskin is the most important indicator. This is only my opinion and you must take it to Louis Vuitton boutique to verify authenticity to be 100% sure.
