Our copper Butterfly Rain Chain is a decorative alternative to the downspout or rain gutter pipe. In Japan, rain chains or "kusari doi" have been around for hundreds of years to provide a beautiful and functional watercourse for rain. Today, rain chains are found on homes and temples throughout Japan for their beauty and cascading water. Simply insert into your existing rain gutter drain hole or place it on a corner eave of your home or patio. Watch the beauty of water cascading down and over each cupper cup.
