Our American Made Koala Kloth uses a technologically advanced ultra fine Japanese microfiber yarn that's extremely strong and generates no particles to stick to your glasses. The ultra dense material has incredible absorption and its honeycomb matrix design catches and holds on to surface contaniments from your lenses and screens so they get removed and stay that way. Our American Made Koala Kleaner, used in combination with a Koala Kloth, easily cleans off oils and grime left on any lens or screen without any streaks. Great for use on eyeglasses, sunglasses, reading glasses, laptop screens, iMacs, Macbooks, iPhones, Smart Phones, and touch screens all of kinds, especially tablet and automobile screens like your Tesla may have. Bundle includes 1 6" x 7" Koala Kloth and 2 8 ounce Koala Spray Kleaners.
