Dirty phone screen? Rub it on your shirt.
You know how devices these days tend to get fingerprints, dust, and smudges easily no matter how careful you are. Instead of bringing along a cleaning rag and wiping it constantly, you can just use the Genius Microfiber Pocket Tee. This shirt comes with a microfiber pocket containing a sewn in microfiber flat that can be used to wipe your phone screen, tablet screen, camera lens, or anything shiny that needs to be buffed. It can even be used on your reading glasses.
