(1) Traditional "Wazarashi" method, gentle on the fabric The Wazarashi method gently cleans the fabric for 3-4 days without stretching or pulling it. This process allows for thorough treatment of each individual cotton fiber, effectively removing various impurities. Because it doesn't stress the cotton fibers, it creates a pure cotton gauze with a fluffy, soft texture not found in typical fabrics. (2) Coverings gentle on sensitive skin: Certified by the international standard Oeko-Tex 100 and recommended by the Japan Atopic Dermatitis Association Oeko-Tex Standard 100 is a globally unified testing and certification system applied to all stages of textile manufacturing, including raw materials, with the aim of eliminating the effects of harmful substances.
