The Centers For Disease Control now recommends wearing masks in public places like grocery stores and parks. These disposable ear-loop utility face masks have a three-layer design, with a non-woven exterior and melt-blown middle layer. Masks are packaged in boxes containing 50 pieces each inside. These masks are not CDC-approved for medical purposes. Masks are not washable and are only sold blank. Includes moldable nose clip, 4.5" L x 0.15"W.
