Corn leather is a new generation material made from corn and wheat fibers. Thanks to natural processes, it is very resistant to dirt and scratches. Keep the cardholder in an ESTIMON cotton dust bag. In order to clean it, remove any dirt with a cloth soaked in water and a small amount of natural soap, and from time to time refresh it with colorless, natural wax or face cream. Plant-based leather does not contain chemicals and does not like them, so the care is very simple!
