Faux leather is an artificial leather that is meant to replace the real thing. It can be used in clothing, upholstery, and other items. It is either made from polyvinyl chloride (PVC) or polyurethane (PU). PVC faux leather is not breathable so it is more commonly used in cases and book binders. PU faux leather is softer and breathable, and is more commonly used in clothing and upholstery.
