Compact enough to store in almost any bag. The kit comes with a 2 ounce lens cleaning spray bottle and a microfiber cloth. The cleaner is formulated to work on all types of coated lenses including lenses with anti-reflective coating, Blue Light Blocking, prescription, reading, sunglass, binoculars, riflescopes, camera lenses, and other optics. ZEISS cleaners are developed to remove dust, fingerprints, and grime without stripping away the lens coating.
