In Japan, rain chain or "kusari doi" have been around for hundreds of years to provide a beautiful and functional watercourse for rain. Our copper Tulip rain chain is a decorative alternative to the down spout or rain gutter pipe. Today, rain chains are found on homes and temples throughout Japan for their beauty. Their cascading water provides an unforgettable experience. Simply insert into your existing rain gutter drain hole or place it on a corner eave of your home or patio. Each cup disconnects for ease of shortening or lengthening.
