SIWA's paper collection, is produced by the Onao paper company in Japan and designed by superstar industrial designer Naoto Fukasawa. The remarkable aspect is the Naoron* paper itself, invented by Onao, which doesn’t rip, is highly water-resistant and can carry heavy loads (tested for up to 10 kgs/ 22 lbs). Onao is a family run company, with more than 150 years of papermaking history in beautiful Yamanishi, a rural area near Mt. Fuji.
*Please note that all items are either made of "soft Naoron" or "hard Naoron": "Soft Naoron" is made from wood pulp and polyolefin fibers - the paper quality is soft and supple; it is hard to tear and has excellent water resistance. Eco-friendly "hard Naoron" has a paper texture (increases with use) and includes polyester fibers from recycled plastic bottles and textile products. Durable as well as highly water and tear resistant.
