Realistically, if you use any decent wallet that has dividers, you'll get most of your wear and tear from inserting your card into card readers and swiping than from keeping them in your wallet. But I use one like this and I really like it:
It's the
Louis Vuitton Damier Infini Multiple Wallet in Vert Acide. I have the
Slender Wallet, which doesn't have the banknote divider and the card holders are symmetrical. Both are very slim and the leather is very soft. It's no longer made in this color, as it was limited to one summer, but the darker colors they offer now are easier to keep clean anyway. They offer complimentary hot stamping of your initials on them too.
