Congratulations, you have found the only company, Fluent Ink, that offers an iPhone case that not only protects your iPhone, but also gives you flexibility in its use. Alone, iBillfold2 Credit Card Case protects your iPhone and carries a few cards and some cash. When desired, the iBillfold2 Credit Card Case can be attached to our premium leather wallets to expand functionality when you need to carry more items with you. No other iPhone wallet / case combination allows you to carry multiple cards and money in such a thin and flexible partnership of style and function while allowing for phone protection and independent use!
