This rain chain consists of straight cups in three different lengths. The spacing between the connected rain chains are unified with the spacing at which the water flow is most gracefully visible. Rhythmically connecting cups of different lengths, the simple yet refined shape enhances the flow of rainwater in an appealing manner. The lines connecting the rain chains and the cores that regulate the flow of water inside the Toh product line are all made of stainless steel, but the Toh line can be made with copper as well.

Made in Japan
