The unique, sculptural fish shape will add an artistic touch to your home. Hundreds of years ago, the Japanese developed rain chains as a way of turning falling rain from a roof into a cascading and enchanting water show. Forget about ho-hum downspouts. These linked copper funnels and channels allow rainwater to playfully and gracefully dance downward, producing a pleasing sound as it travels toward the ground. A natural patina will develop over time, adding to the character of our quality-constructed rain chains and cups.
