Are you from the generation when mood rings were a thing I am not that old but I do remember kinda being a thing for my generation So SlickWraps a premier source for quality consumer electronics protection and accessories decided to make a wrap using this same technology used in mood rings the material changes color based on temperature  to try it out make sure your hands are warm the magic won’t work if your hands are cold from just coming in from outside this product is available both in a wrap form and Slickwraps newest product The Case  I recommend since wraps over time won’t last if you handle your phone a lot I have found myself to be playing a lot more with the phone then normal Now to add onto the awesomeness Included in every package is a Slickwraps HD Screen Protector and if you get The Case Mood Series you will also have a front and sides included in the package  personally when it comes to the mood series out of all the skins you could choose from SlickWraps picking the mood series on your iPhone 5/5s just makes The Case
