This Lenspen Cleaning Kit consists of a Lenspen with a retractable brush at one end to remove dust from hard-to-reach places on your camera or lens. The other end has a round concave felt tip with carbon-cleaning technology to clean grease and fingerprints from the surfaces of glass. The Hurricane Blower will remove tiny particles of dust off your camera and lens and is also safe to use on your camera's sensor. The MicroKlear cloth is made from soft suede microfiber that is safe to use on all surfaces and won't scratch glass.
