Perfect for cleaning glasses and sunglasses lenses. Thanks to its active carbon technology, it does not scratch the lens and gently removes grease stains and other dirt. To remove stubborn stains, breathe on the lens and then clean it with Peeps. The cleaning surface can be refreshed with the activated carbon sponge in the cap, so peeps can be used hundreds of times. No liquid or alcohol is needed for perfect cleaning, as the activated carbon does not run or dry out. It is convenient, safe, simple and quick to use, and its small size makes it easy to carry.
