An ultra-fine fiber cloth cleaner that cleans fingerprints and dirt on the lenses and monitor parts of glasses, sunglasses, smartphones, PCs, etc. Since it has a special ultra-high-sound cut technology and high-density processing and does not self-generate, dust does not collect when wiping. Therefore, it is also used for clean rooms that handle precision equipment. It absorbs more than twice as much water and speed as cotton cloth, and has a fine-grained leather-like feel that thoroughly wipes both water-based and oil-based stains. If it gets dirty, you can wash it and use it as many times as you like, so it is an ethical item.
