Honestly thought that it was not concerned so much with the mask, finally PM concentration which can not be hidden in the media at last ... It will not be fancy. I have been masking since it is a severe hay fever since long ago. But ... but ... I can not see the mountains! Is it? 200 meters ahead is hazy! Is it? It is purchase with credible Monotaro san who thinks to purchase full-scale mask receiving shock. In other places it does not correspond to pm, but there are plenty of places to sing. As a specimen impression of the product, it is completely sealed completely. Nose wire? It is rugged and hard. Lol It is hard when you attach it for a moment, so you may have difficulty when making close contacts. The fabric is also thick and it is really strong and I think that 10 times the market mask has strength. Although the fabric is thick and hard, it is very flexible and it fits perfectly along the skeleton of the face and it is amazing. The air valve does not operate Even with weak breathing, I do not feel breathing, and the valve works firmly for strong breathing and it is perfect. If you are doing strong breathing like driving a valve on a tone and you are breathing excessively, you can hear a crackling simmus (> <; often with a mask you will hear that the strength of the rubber is weak and it cuts, etc.) I strongly recommend you to cut it! I have not seen anything sturdy ^ ^; It is designed to be applied to the back of the neck and above the back of the head so it looks like an ordinary mask Please note that putting on the neck and ears is quite painful.I can not go back to masks and cheap masks on the market any more Thank you for being truly asshole
