The best way to describe the wearing of the wallets is that it's like jeans. They wear in, but don't really wear out. Over time, the material can get a bit wrinkly and the printing can get lighter so the natural swirls of the material start to show through more. I've found that the biggest determining factor in how long it stays looking fresh is how much stuff is in it. The more full, the faster it will show signs of wear, but some people like how it looks more and more.
I also improved the printing between V1 and V2 of the Original style by finding a print house that specializes in Tyvek and the MICRO uses the same printer as I used for V2.
