An Irish Prayer: May those that love us, love us, And those that don't, may God turn their hearts And if he doesn't turn their hearts, May he turn their ankles, so we'll know them by their limping. Yikes. We won't break your ankles, but we're sure you'll love this Emerald green mask, made with pure sustainable viscose fabric. The masks are light and breathable, with a pocket for a PM2.5 filter. Cinched straps keep this comfortable all day long. Fabric content: 95% viscose, 4% elastane, 1% PET. Each mask comes in a white 3.5” box with a clear vinyl lid, as well as a complimentary PM2.5 filter. Don't sell masks in a bag.
