ONAO is a Japanese manufacturer of (washi) paper. They recently collaborated with industrial designer Naoto Fukasawa and launched SIWA, a product line of everday items like bags, stationary products and even fashion wear. The paper is strong, tearproof and highly water resistant. It looks beautiful almost like leather. I would love to stroke it with my fingers. The best, the so called Naoron paper is non-toxic even when burnt.
