Hello all, I'm looking to buy a YSL WOC preloved but it appears to have a blank white card inside one of the card slots, is this correct? It put me off, as I know there are some strange paperwork/cards can come with reps and it rung alarm bells but this is my first ysl, I only have LV and know exactly what to look for. It seems to have everything else that looks correct. Just scared to drop that amount of money and not sure how in person once I receive it I can auth it. Thanks all!
