The shells are arranged in a triangular formation, with the largest one in the center and two smaller ones on either side. The labels on the shells indicate that they are of various sizes and shapes, with some having intricate designs and others having more simple designs. The colors of the shells range from light brown to dark brown, and the shells have a glossy sheen.
