When I bought medicine at Rakuten it gave me this mask with a bonus. I tried using it very well, and pollen pollination work did not hurt my throat and nose. The appearance is somewhat strange to be like a duck beak when you put on the mask, but I think that it is easy to breathe thanks to this space. This time, I had the opportunity to buy it cheaply at your company and I think that I will stock it. It is hot this summer, so it seems that the amount of cedar pollen scattering next spring is large. This mask will definitely be useful.
