I've used thoe nylon velcro tri-fold wallets since I was in college. They look a little tacky, but I just like them. When I saw an ad for this wallet, I thought I'd give it a try. When I opened it my first thought was that it was flimsy, that's why it's skinny, but I was wrong. I noticed the difference as soon as I transferred everything into it. Full, it was about half the size of my old wallet empty, and it's not flimsy at all. The material is thin, but it's really strong. I've been using it for a couple of weeks, now, and I'm very happy with it.
