As I’ve mentioned before, I don’t keep the same cover on for more than a week. I have multiple colors and styles to keep me interested. This case, the Innovez iPhone 5 Life series, arrives in two parts. The hard back cover and the soft inner sleeve. The delightful part about this case is that you can mix and match the covers and sleeves, maximizing your options for a reasonable cost.
Note: Amazon carries the product, but doesn’t carry the extra sleeves. You may want to buy directly through Innovez to get the most options.
This might be overkill, but I also change wallpaper with each cover to make sure the wallpaper matches. I use the Wallpaper HD app to find new images.
