I tried so many styles of wallets before using the Original Taxi Wallet.  Now it is the only wallet I will ever buy.  It doesn't look so extraordinary but it holds an incredible amount of cash and receipts, especially after it has broken in.  It is extremely durable and outlast other wallets 4 to 1.  I hope they will never stop making these wallets.  Maybe I will just have to stock up on these just in case.
