Review on 📱 MONASAY iPhone 7 Wallet Case/iPhone 8 Wallet Case/iPhone SE 2020 Case: Flip Folio Leather Cover with Card Holder & Screen Protector for Apple iPhone 7/8/SE2 by Emmanuel Winschel

So the case itself and the protective film are good, but it seems to be a design flaw. They include a warning that the magnet on the front can ruin your credit or debit cards if placed in the wallet with the tab facing out. I just got it and don't know if it's really going to ruin cards, but it seems dangerous if you just absent-mindedly put your card in a wallet and the magnet is right there. Do other cases I've had have a magnet on the back of the case? If the magnet doesn't ruin the cards then this is a great case. But when I saw the warning I got worried!
