iPhones are marvels of technology that manage to pack an amazing array of features and functionality into a very small package. But even with improvements to their durability over the years, including water-resistant screens, they’re still not the most robust of devices and can be easily broken with one bad fall or footstep. In fact, if anything, their increasingly thin design over the years has made them more susceptible to certain kinds of damage. That’s why a case is an absolute must for anyone who wants their device to last. And with a seemingly endless variety of colors and designs for even heavy-duty cases, they’re a great way to personalize yours.
