These slippers are made of paper produced by the centuries old Japanese process of washi-suki. The slippers are made of RPF NAORON (special paper, to which recycled polyester fibers have been added) and the SOFT NAORON which is containing wood pulp and polyolefin fibers (both these papers do not emit noxious fumes when burned).
The footbed is filled with a high quality of felt and the sole is covered with artificial leather. The slippers are flexible, water resistant as well as surprisingly strong and comfortable. The SIWA series is a creation of the Japanese paper (washi) maker ONAO and industrial designer Naoto Fukasawa.
