This wallet is perfect but has it's flaws. An original prototype made while we finessed our final project sometimes just isn't quite right. In this version, we have an eyelet on the bottom side of the wallet flap where we originally wanted the chain to come out. In the end we realized the chain hole is better suited at the top of this flap and so we moved it. We also made the coin pouch on future versions about 1cm larger which isn't noticeable but it was to us!
