Kusari Petals Our Kusari Petals rain chain has a Japanese Petal design, with a rustic copper finish. Like our Copper Blossoms model, this style is also a classic traditional Japanese style rain chain design. It is both unique and simple, while retaining complex accents. Like all of the copper rain chains, this will develop a wonderful patina over time. It comes with its own attachment piece for easy installation. Cup: 2.5"H x 2.5"W
