Big Skinny Wallets hold the most.
I have used these wallets for close to ten years. The one I was using before this one was a more minimalist style and it still held a lot. I finely upgrade to one that holds about ten more cards and it still doesn't look like George Castanza's wallet from Seinfeld. Thank You Big Skinny.
ProsYou can hold so much more than a regular wallet that you will want to and will.
ConsThe only con is trying to over fill the wallet, but if you stack all the cards you can fit in the wallet on top of each other you will realize that is still really, really hard to do.
