Safe to use on all optical lenses, filters, sensors and glass, the LensPen MiniPRO is designed to easily remove fingerprints, dust and grease. The concave-shaped cleaning tip is perfect for use with on convex surfaces, such as lenses, and a retractable brush makes it easy to sweep particles away. The non-liquid cleaning compound means better control while removing dust, and it’s designed to never dry out. Simply replace the cap after using the LensPen to ensure the surface of the cleaning tip is refreshed and ready for next use. The ultra-compact size of the LensPen MiniPRO (only 3.7” long and weighing less than an ounce) makes it easy to pack in any size gear bag.
