I'm looking for a wallet to carry 6-8 cards (2-3 of them embossed) and usually 10-15 bills.
Here are my preferences:
The wallet needs to be able to accomodate US and foreign bills.
The wallet can be made of leather and/or metal (I assume Aluminum). I don't like plastic or cloth or ripstop fabric wallets
I prefer standard flat placing for the bills, not external to the wallet nor that they be held by some metal clip or rubber band.
I've looked at the Secrid wallet, it can't comfortably hold more than 2-4 bills max.
The Wally BiFold Wallet seems nice but it holds the bills by a metal clasp that seems fragile and the rubber contour around the wallet will certainly deteriorate quite quickly. I once had a premium case for one of my phones that basically had the same design - and that's what happened to it.
I also looked at the Exentri, but their Web site does not mention the bill capacity. The Cascade Wallet also looks nice but again, I don't know how many bills the extra leather cover can hold.
I'd appreciate your recommendations.
