The NiSi Gold Lens Pen is a double-ended cleaning pen that incorporates a soft, retractable brush along its top and a soft, felt, carbon-compound cleaning pad at its bottom. While the brush is effective for clearing dust off coated optics or LCD screens, the carbon-compound cleaning pad can be applied to remove oil or moisture from those surfaces. This lens pen also features a built-in pocket clip and a removable cap for protection of the carbon-compound cleaning pad during storage or transport.
