These are a 4 layer washable face masks, with an added layer sewn in.
- Two of the layers are a woven fabric
- One layer non woven
- With an extra brushed cotton layer sewn into the middle section
- 4 layers in total
There is a wire bridge on the nose for an extra close fit.
Both sides of the mask are made with different fabric so that you don't get the front and the back of the mask mixed up.
The elastic can be removed and replaced with a different elastic, ribbon, cotton tape ect. So that you can tie it around you head if you would prefer or have a different style/type of elastic.

These are NOT medical grade
