I've been using this as a wallet for year. I love it.
I'm on my second one in about 5 years, replaced because the first one was stolen.
When I get caught in the rain on the motorcycle I don't panic about my wallet getting ruined. I've accidentally ran it through the washer (more times than I care to admit). Whenever someone sees how slim my wallet is they are always impressed and want one and want the details of where to get one too.
It fits into any with women's pants pocket I've tried. I think that is a miracle in it self, seeing as women's clothes are notorious for tiny pockets.
It fits along side my concealed gun in my vest pocket without extra bulges.
The only downside is trying to carry cash money, not something I do on a regular basis. Anything more than about 10 folded bills and the wallet becomes thicker and bulkier. The best fold for American money is folded in thirds so it makes everything thicker.
ProsHold plenty of cards for everyday use
Washable (don't advise leaving your cards in the wallet when washing)
ConsHas a hard time hold large amounts of bills without becoming bulky.
