Can't Copy Carhartt

Overall a nice wallet
Color: Carhartt Brown (Trifold)
The card slots are a little tight so removing cards can be a hassle. On the other hand, cards won’t fall out if you invert the wallet. I expect the card slots to loosen up with prolonged use. The wallet is great in all other respects.
