Minimalist Wallet and Key Organizer

I made this wallet because there is no wallet that satisfies my needs in the market today, not even ones that cost $100 ++. I need a minimalist wallet with the smallest footprint possible (as big as a credit card) that also holds my keys. I can go with a feature full wallet, but realistically my 4 keys and 5 cards are the things I really need to bring every day. The key organizer is a must for me because I'm really forgetful and lost/forget my keys all the time. With it being attached to my wall
