A durable periostracum tightly covers the exterior. The outer lip is thick and has a smooth inner surface, while the columella is calloused and exhibits three folds, with the central fold being notably large and angular. The shell’s color on the exterior is whitish beneath a dark brown periostracum, and the aperture appears porcelain white.
