Tulip Rain Chain and Rain Basin...In ancient Japan, homeowners knew that downspouts were necessary to help guide rainwater to the ground. Useful, but visually boring. So they invented “Kusari-Doi,” or “rain chains.” Instead of a downspout, it’s a functional water feature that shimmers and shines, and sounds lovely when it rains. Great idea, right? Install your own Kusari-Doi instead of a downspout, and you’ll enjoy April showers like never before!
