Older millienal. I bought the phone case wallet. Opens like a book. I'll admit, when it arrived and I slapped my new phone in it, I realized I've only ever seen old man and women use this kind of case. Felt weird for all of ten seconds. I fucking love it.
That being said, I am surprised how many people are asking where people keep their cards and cash. A lot of people literally just use pockets. Like, they raw dog cash, id, some credit or debit cards and got like 2 or 3 loose keys. Don't get me wrong, they are crazy people and I will literally laugh at them when they wonder aloud where their card is, they JUST had it. But it's a lot of em. (Worked in retail over a decade, still work in a field where I ask people for their stuff and payment).
