The 3-layer cotton mask
has drawstrings on the sides that allow you to adjust the size perfectly, and they won't push you behind your ears after wearing them for a long time. The inner layer is made of non-woven fabric.
The mask does not serve as a replacement for full-fledged medical devices or respirators, but it can reduce the risk of transmission of viral diseases. The color of the strings may vary.
Wash your hands with soap and water or use an alcohol-based disinfectant before putting on or removing the mask.
