I just bought this wallet for the 2nd time. First time was 8 years ago. It cost $19 then, and $20 now - refreshingly reasonable.
My first wallet is now worn out and frayed along the top and bottom edges. I probably should have replaced it 2 years ago, so I'd say the lifespan is 5-6 years before considerable wear.
I love the size and design. I'd pay more for a more durable material, but shopping around I found everything else in this style is slightly wider or taller and/or has tedious card access.
This can hold about 15 cards with about 10 folded bills before it starts to stretch.
