The natural color of scallop is white fan-shaped texture, and the natural color of abalone is blue-green irregular texture. The shell can reflect natural and shiny luster under light, which couldn't be achieved by artificial products. In order to do more designs on shell, you can also print different colors or patterns on the surface of the shell. The following product pictures are as example.
