Review on 📦 Conveniently Packed Black Layers for Efficient Handling and Storage by Sean Burnett

Received much quicker than stated. This makes breathing a little more difficult than through a normal fabric mask with an additional filter. However, after fully opening and shaping the bridge of the nose, the mask seems to fit very well and feels secure. The mask then has an air pocket around the nose and mouth. I won't do much in it but it will fit well etc.
