SIWA : Paper like you've never seen before
The name SIWA is both a reversing of the characters in the word washi (wasi), and a word meaning, "crinkle" in Japanese. As with leather goods, these washi products are lovingly, individually crafted. Nice and light - perfect not only for everyday use, but for use when traveling or as a side bag.
Naoron is a new paper-like material developed with the traditional washi-suki paper manufacturing technique, by the Japanese paper maker ONAO based in the Ichikawadaimon area. It is soft to the touch, light and flexible, yet very strong. The material is also superior in water resistance and durability that does not tear easily.
While maintaining the excellent lightness and distinctive texture of Japanese paper, ONAO developed a new type of Japanese paper that expands the possibilities of paper. That is “Naoron”. With the flexibility of Japanese paper, it is highly durable and water-resistant that does not tear. Naoron brings traditional delicate paper far closer to us, in our everyday life. The SIWA series is a line of products for everyday use that are made using this excellent material.
In collaboration with well-known industrial designer Naoto Fukasawa from Yamanashi, ONAO based in the area with the 1000-year-history of Japanese paper making launched the SIWA brand.
The graph here shows the strength comparisons between kraft paper used in general paper bags and Naoron. Needless to say, general paper becomes very weak and much easier to tear when it gets wet. The graph indicates wetting kraft paper (WET) had a dramatic influence on the strength of paper when it is pulled and torn. (Tested in 2008) . However, the opposite is true for Naoron. If anything, the new material is increased in strength when it gets wet. In the tear test, you can see a significant increase in the strength of Naoron when it is wet.
Naoron is made from wood pulp and polyolefin fibres using the washi-suki paper manufacturing technique. It is drum-dried at a high temperature of 70 to 80 degrees, which allows pulp and the fibres to become interwoven, resulting in durable paper.
Hard Naoron is created from all polyester fibers, of which 60% is made from recycled plastic bottles. The more both Naorons are used, the softer they become offering you the good fit to the hand. Please relish the distinctive crinkle texture and soft touch of our unique paper.
How to care for the SIWA products:
Fill a wash bowl with room temperature water and fully dissolve an adequate amount of detergent. Make sure to completely immerse the SIWA product in the water and hand-wash it by gently pushing it up and down. The paper fuzzes if rubbed hard. Then, gently rinse the product with water once or twice until it has no remaining detergent. Absorb moisture with a towel and completely dry the product at a place out of direct sunlight. Do not use an electric device that uses heating elements, such as a hair dryer or iron.
Soft Naoron is a paper developed by Siwa from wood pulp and polyolefin utilising the washi-suki paper manufacturing method. It is soft and flexible, highly water-resistant and does not tear easily. Soft Naoron does not emit noxious fumes when burned.
Hard Naroon, RPF Naoron: (Recycled PET Fiber Naoron) is a paper created using the washi-suki paper manufacturing method from recycled polyester fibres from used plastic bottles and textile products. While having the distinctive texture of paper, it does not tear easily and is highly water-resistant. RPF Naoron does not emit noxious fumes when burned.

Regarding handling of the products:
• Pull into shape before use.
• Please note that dark colours may fade or run.
• Do not wash.
• Clean with a well wrung out, damp cloth.
