Flip phone cases: Flip phone cases are similar to a wallet style phone case . They can even be flip wallet cases or just a flip case without the wallet aspect. They usually have an inner polycarbonate shell, and the front flips down vertically from the top or the bottom, so it flips open essentially on the short edge. The draw of these cases is the look of them, in that they are a leather style. They are protective of the front, back, and sides of the devices, and usually come in a range of colors. They are not as popular as the wallet style case, however.
