Cards falls out
Material Type: Leather, Color: Coffee8143
It's a beautiful wallet and would literally be perfect for what I need, but for whatever reason the pop up section of cards that is the main feature doesn't hold cards well. My cards especially my debit card fall out easily and it is really inconvenient and makes it impossible to use that main slot. I got my wife a different wallet from the same brand though and that wallets pop up slot holds the cards perfectly and locks them in well. I guess this wallet was an older model?

. It's great for storing credit cards
Material Type: Leather, Color: Black8141
I bought this as a gift for my husband. It's great for storing credit cards. They don't fall out and slide out with a side lever. And as far as I understand, it has protection against scammers who could scan your pocket and steal all your money. It's very well made. Genuine leather. Comes in a beautiful craft box.
