I don't know if this is the right area to be asking this but here it goes. I would like a very small "bag" or coin purse to put credit cards in, something like 3" x 4". I have seen in another thread/forum the smaller accessories that are available, but it looks like the smallest square coin purse available is "The coin purse" which measures 4"x6" (or something close to that). Does Balenciaga make the mini mini still? (or something close?) --Thanks for the help!
