JayJay Pollution Dust Mouth Mask PM2.5 Carbon Filter Washable Cotton Respirator With Replaceable filters

In my country, fine dust is a big problem now. So I bought this pollution dust mask.Yes, it looks a little pretty.But it doesn't work well because the wire in the mask is not strong enough to hold properly.And my mask doesn't look pretty because it contains the end of the fabric.I think it's a crapshoot and I was out of luck.

it's good item.
