Perfect for cleaning the lenses of cameras, cameras, binoculars, telescopes, objectives and other optical devices. Thanks to the activated carbon technology, it does not scratch the lens and gently removes grease stains and other dirt. To remove stubborn stains, breathe on the lens, then clean with the Lenspen. The active carbon sponge in the cap can be used to refresh the cleaning surface, so the Lenspen can be used hundreds of times. When the cap is screwed back after use, the cleaning head is cleaned and refilled with carbon powder thanks to the activated carbon-soaked sponge placed in the cap. For perfect cleaning, neither liquid nor alcohol is needed, the carbon-based cleaning powder does not flow or dry out. Its use is convenient, safe, simple and fast, and thanks to its small size, it is easy to carry.
