You asked a while back, so we bought a bunch of US-made cotton-lined masks with filters and adjustable earpieces ... and then none of our designs looked good on them. UNTIL NOW!
NOTE: Our reordered larges do not have adjustable earpieces but the regular elastic kind, and do NOT come with a slit for a filter.

They come in large, medium, or child's size, with FREE SHIPPING in the US!
