Review on Men's Leather Zipper Wallet with Advanced Blocking Technology for Enhanced Security and Organization by Nathan Jankowski

Well made nice wallet. It can take a lot. It will take some time. I had trouble unzipping initially because the center piece of the card holder on one side / ID window on the other side slipped out a bit making it difficult to zip up. Be patient. I just pushed it back (1-2mm) and then it closes normally. After 2 weeks it's not that strong, but after 4 weeks it's rare. (Plus, lip balm can help with tricky zippers!) It lubricates just enough to get the zipper's "teeth" in place.
