Sticky microfiber cloth’s silicon back makes them easy to peel off, clean and re-stick back onto the phone or other electrical device. Sticky cloths are made with a woven microfiber cloth which can safely clean most sensitive surfaces such as smart phone screens, camera lenses and even glasses. The silicon sticky back is reusable and if it gets dirty, simply clean it with water and it will get sticky again. We can custom make any shape or size, so contact us if you have any custom requests.?
