This plexiglass support is inserted in the men. It is located at the bottom of the mengane. Thanks to the indentations on the sides, it is very stable. In this way, it captures some of the droplets that are emanated from the mouth or at least deflects them in their horizontal diffusion movement.
Note: even if some droplets are caught, this support does not represent antivirus protection for men, it is not a medical device. Remove the thin protective film on both sides before use.
