Phone fingers are prophylactics for your digits so you don't smudge your precious iPhone screen. They come in small, medium, large and extra large, and you can get a bag of 25 of them for around $15. They are stupid and ugly, like my girlfriend. They also make you look like you've had your hand up your ass. As stupid as they are, I'm still buying a pack of the small (I wish they had extra small) to test as reusable condoms.
