I'm interested in purchasing this case. I just have a couple of concerns regarding it first that I want to ask in case anybody has this case or has had cases just like this. First off, this case has a magnetic strap. Will that ruin my credit/debit cards because I've heard magnetic stuff ruins your cards. And second, with the cards in the wallet can that scratch your display? I'm planning on getting a screen protector later down the road but until I find one that fits my needs, I'm worried any cards especially debit and credit cards have the potential to scratch my display. So if anybody has this case, how is it? Do you or have you experienced any issues like the ones I'm asking while using it?
