Features: nose wire, soft elastic with silicon bead to adjust fit, two layers of non woven fusible interfacing to help with structure and filtration, and a neck strap to wear the mask as a necklace when you don't need to be covered up. Never lose your mask again, and stop putting it on dirty surfaces when you take it off. You're gonna love it.
Masks are 4.5 inches wide (folded) and 6.5 inches tall. One size fits most.
