Microfiber is a unique, durable, innovative, hypoallergenic material. The complex fiber structure consists of two synthetic fibers: the outer surface is polyester (20%) and the inner part is polyamide (80%). The special structure of the fibers allows all types of dust particles to be literally drawn into the fiber, keeping it securely. Microfiber removes germs and bacteria from the surface. The microfiber cloth is designed to care for any surfaces. The napkin is ideal for cleaning windows, glass, mirrors, crystal, optics and any glass surfaces.
