We are excited to present our patented design which is not only extremely effective but also incredibly easy to use. Just apply a bit of pressure as you roll it over your cell phone, tablet, iPhone, mac or computer screen to keep them looking bright and new, as professional as you feel with a smart snazzy touch that will keep you looking great and feeling awesome. Promise! And not only will you see fingerprints disappear right away, it goes a step further and removes bacteria on your screen as well for an even deeper cleanse. After several uses, simply rinse it under warm water and allow to dry. And measuring in at only 3 ½ inches, you can easily stick it in a pocket or purse while on the go for an easy touch-up whenever you need it!
