I came across a Nikon branded LensPen on Amazon and it piqued my interest. It had good reviews and I did some googling and found its made by another company and branded for Nikon. It has good reviews whether its Nikon branded or not.

With the good reviews and the Nikon seal of approval I took a shot.

It works GREAT! Field cleaning of any optic is very easy. Brush away any loose debris and then use the non liquid cleaning end to get rid of fingerprints or other smudges. I've used it on binoculars, scopes, red dots, and camera lenses.

$9
