This is the "Hatsutomi Hikaru Vi-fresher" high-performance non-woven wiping cloth from Kusumoto Kasei Co., Ltd. The wedge-shaped edges of the microfiber powerfully remove dirt, and because it has not undergone chemical treatment such as with dust-attracting agents, dirt does not re-adhere. It can be washed and used repeatedly. It can be used on eyeglasses, camera lenses, mirrors, accessories, multimedia devices, smartphones, cell phones, game consoles, computers, LCD screens of televisions, CDs, DVDs, and more. [Material] Polyester, Nylon [Size] 20x20cm Although it is unused, please refrain from purchasing if you are sensitive to items stored at home. Thank you for looking.
