But do you think 4-5 is loose only b/c you usually have it loaded up w/ more? i.e., does it get stretched out a little?
the material is great even when you stick in a load of cards and then decide you don't need that many in, the material adjusts to the new amount of cards you put in your wallet.
The wallet is not made to be suctioned tight with having no cards inside, it's designed to have enough room to put in 3/4 cards In each side at the minimum, with those minimal amounts the wallet we'll stay fine and snugg.
