A few years ago, your phone spent more time on your ear than in your face. Thanks to texting, apps and the now-ubiquitous touch screens, mobile devices went from convenience to necessity. Everyone's guilty of using time in the can to check e-mail or social media, but while we can always wash our hands—we can't really do the same for our phones. Enter GoSwype—the microfiber cleaning cloth that claims to kill 98% of germs and harmful bacteria like Staph, E. coli and salmonella. The tiny cloths are only 3.5 x 2 inches each, and cost a mere $2. They do their job for about 2 weeks of use. At that size, they're way to small to double as a pocket square, but they're super light and portable (and even come with their own case). They definitely make quick work of removing smudges from your phone or tablet screen, which comes in handy in steamy weather. Plus, they come in a bunch of colors and patterns, from school symbols to menswear-appropriate designs. Here are few of our favorites from the current lineup.
