● Koyasan Tsumugi: It was born by making effective use of cedar and cypress, which are not used as wood, which are produced when caring for 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. The rubber straps that hang on the ears are soft round strings that can be adjusted to your own size. 【size】 Width approx. 17.5 cm× length approx. 10.5 cm * It will be the size value measured by placing it on a flat place. * Since it is produced by hand one by one, there are some individual differences in size. 　Thank you for your understanding. 【Quality】 60% cotton　 Unclassified: 40% fibers (yarn made from Koyasan cedar cypress) 【Precautions for use】 ・Be sure to wash before using for the first time. ・This product is not intended for medical use. ・This product does not guarantee the prevention of disease. 　To prevent infectious diseases, please take precautions such as hand washing and disinfection as appropriate. ・This product cannot be used in places where harmful dust or gas is generated. ・ In the unlikely event that symptoms such as itching and rash appear, 　Stop using the product immediately and consult a doctor. ・Should you feel sick due to the smell of the mask, discontinue use immediately. ・Do not use near fire. ・Keep out of reach of children.
