These mask inserts are made from a very thin stainless steel frame that is easily formed to fit the contours of anyone’s face, and have two holes on either side for easy attachment. Easy adjustability helps create a better seal against the face for added protection and is also very effective at preventing foggy glasses!
The straight style work best on the pleated masks that are straight across the top. When flat these are approx 3" long and 3/16" wide.
The contoured style insert works best for masks that are contoured/fitted across the nose. When flat these are approx 4" long and 3/16" wide.
