Penny loafer with heel made of fine brushed black calfskin with heel and platform on rubber sole. Regular fit. MATERIAL: Abrasive leather is a type of finish to which a wax layer has been applied to the surface that makes it very uniform and resistant. It is hand brushed to give a glossy or matte finish. TAKE CARE: Brushed skin care begins with removing dirt with a soft cloth, followed by applying a wax of the right color to nourish and protect the skin. Then scrub vigorously with a polishing glove to polish it.
