The Japanese papermaking company Onao and designer Naoto Fukasawa have teamed up to create the Siwa line of products. All Siwa products are made of Naoron, a special type of paper which consists of wood pulp and synthetic fibers. Onao based its production upon an ancient Japanese manufacturing process: washi-suki. The Naoron is water resistant and hard to tear while still retaining its distinctive paper texture. In the Siwa products Fukasawa aims to emphasize the characteristic wrinkly texture of paper. The name Siwa derives from the word ‘Shiwa’, meaning ‘wrinkle’ in Japanese. At the same time it is an acronym for Washi.
