So you're torn between the choice of a card wallet and the good ol' billfold. On one hand you want something thin and practically invisible and on other hand you wouldn't mind sticking to what you're used to and having the space for all your cards and cash.
How about something in the middle? Parabellum's new version of their Courier Wallet slims down the design and unzips to reveal enough room for all the cards you need and more than enough room for a decent amount of cash. As for the vibrant colors, the ceramic/brass hardware, and the bison leather? That's the icing on the cake.
$200, available at parabellumcollection.com.
