Koyasan Tsumugi: It was created by making effective use of cedar and cypress, which are not used as wood, which are produced when tending to forests. It is a mask made of wooden threads made by crushing wood into small pieces and kneading them into fibers such as cotton. It is a mask that has a comfortable hemp-like tension and smooth touch, and is breathable, so it does not get stuffy and is easy to breathe. In addition, the deodorizing effect of wood can be expected to have the effect of suppressing odors and the growth of germs. (After use, please wash it frequently every day and keep it clean.) The back part is made of double gauze, and the part that comes into direct contact with the skin is gentle to the touch. The color is a natural generative color. It has a simple and natural texture, is easy to fit into any fashion, and can be used by both men and women. Sizes are also available, M size for women and L size for men. The rubber straps that hang on the ears are soft round strings that can be adjusted to your own size.
