My aunt gave me this very wallet for Christmas 17 years ago, and I've worn it pretty much every day.  I only recently noticed that the stitching was starting to come out, and belt loop part was wearing thin and about to rip (the outer zipper hasn't worked in a few years, but I never used it anyway.)  In short, I broke down and bought a new one from Amazon.  I was ecstatic to find out that it was exactly the same as my original!

I thought about getting the old one fixed, and I still might for sentimental purposes.  The leather, the snaps and the chain are all in perfect working condition...  No cracks, no rust.  If you're in the market for a durable chain wallet, I highly recommend this one!
