Since I'm wearing glasses I always the problem that my glasses starts. We are currently renovating a house and as the mask is a must. Day before yesterday I ordered and yesterday arrived the parcel. TOP! I then tested the same mask. Functional top, no tarnishing of glasses. Can also be adapted to the super nose. The small belt bother me now not really. In the construction market suki masks cost in this version betw. 6-8 for! Clear buying and saving recommendation :-)
