LensPen is the solution for cleaning camera lenses, binocular lenses, spotting scopes and other optical items. It is supplied with a handy retractable dust removal brush and a special non-liquid cleaning element. It is also so designed that it never dries out. LensPen is easy to use and most importantly, safe. You remove any particles with the retractable brush. You then remove the cap and wipe the lens with smooth circular motions of the cleaning tip. If smudges persist, breathe gently on the surface and repeat the process.
