The frame of the Bass Player Wall Decor is created using tin, which is powder coated in a black finish. The frame is reinforced using wrought iron wire inner and outer edges. Capiz is an oyster shell and the primary purpose of the oyster is as a source of food. However, the by-product, the shell, can be used for decoration. Due to it being a natural material, the natural colors of the capiz can come through as tans and browns underneath the paint.
