hi ladies...i was hoping to get some of your expertise on gucci wallets. i have noticed that when looking at the continental d-ring large wallet that sometimes there is 6 card slots, and other times there are 12. i tried to notice if its variations in colour or material (canvas/leather), but there always seems to be some variations no matter what the material. is this because they change the style slightly from time to time? are both 6 and 12 card slot options available? is it made for different markets (europe/asia/north america)? i'm starting to wonder if the difference matters significantly or not... any help would be SO VERY APPRECIATED. photos would also be helpful. thanks ladies!
