Protective masks are often unpleasant to wear. The mask clip is very useful to make it less constraining and to adapt the mask to the shape of the face. The explanations in pictures.

Protective masks are sometimes difficult to wear. Either they are too big, so you spend all the time trying to fit them by touching them (which is not recommended), or they are too small, so they fit tightly and the elastic bands irritate the back of your ears.... In short, a real nuisance!
With this mask clip you can adjust the mask to the shape of your face so that it fits as comfortably as possible and protects you optimally. The clip is made of soft plastic and has notches that allow you to adjust the tension of the elastic bands.
