These quite common small shells reach on average 15–20 millimetres (0.59–0.79 in) of length, with a maximum size of 26 millimetres (1.0 in) and a minimum size of 8 millimetres (0.31 in). The basic color of these pyriform shells is light beige or light tan, crossed by three transversal white bands with a zigzag pattern. The base of the shell is yellow or orange-brown with some brown small spots, extended along both sides. The aperture is orange with several short teeth. In the living cowries the mantle is orange-red, with white papillae.
