This fish keeps his eye on your while he swims in the currents of the wind. Black metal frame, 2 in capiz shells (green and blue), Chinese coin and mirror accents. Capiz shells come from pearl oysters, commonly known as kapis. These shellfish are farmed in Indonesia and every bit of the oyster is used. The shells are carefully sorted, dried, sliced, shaped, sanded and dyed. Strung together with strong, invisible, nylon cord, the thin, flat translucent shells provide luminous color. And, when touched by the wind, these chimes produce a delicate tinkling musical sound. In the 1500s, these shells were used as windowpanes in houses; now they are used in all sorts of home decorations, including lamp shades, vases and, of course, windchimes!
