Designed to remove stubborn dust and other particles from the sensor of a DSLR, the LensPen SensorKlear II provides fast, effective, consistent cleaning results. Safe to use on all sensor surfaces, this pen easily removes oily fingerprints, grease and dust. Use in combination with the LensPen SensorKlear Loupe (sold separately) to magnify trouble spots that require removal. An articulated tip helps reach spots that are hard to reach, and no liquids, sprays or chemicals means no residue left behind.
