According to ACS NANO, the study announced the results of a study showing that cloth masks combined with high-density cotton and electro-static materials such as chemical fibers and silk can effectively cover aerosol particles from the air.
We have started to make three-dimensional face masks with two different fabrics. Inner is 100% cotton and surface is 100% silk.
These silk have traditional Japanese pattern which are used for Kimono. The mask is washable and reusable.
The mask is $20 per each.
