Open drawstring for different wearing options
The elastic cotton straps are threaded by an open drawstring, through which any band can be threaded if necessary, so that the mask can also be worn in different ways (e.g. with attachment at the back of the head). If the mask is too wide, the bands can also be easily knotted tighter.
In addition, for an even better fit, the distance between the straps in which the drawstring is gathered can also be reduced.
