too flimsy [SEP] these are great as regular headbands but not so good for strapping your mask to the material is so so soft which is nice from a comfort standpoint but it isn t rigid enough to support the buttons on it so my mask straps just pull the buttons away from the material and fall off i am going to try sewing the buttons through both sides of the fabric to see if that helps but it s annoying that they aren t working for their intended purposeadditionally one of the buttons fell off almost immediately which again doesn t help with the mask situation
