The Kobayashi Overnight Herb & Eucalyptus Face Mask (Fitted Type) is a day-and-night use 3D mask with a herb and eucalyptus scent. It cuts virus droplets, pollen, and PM2.5 due to its filter effect. The mask provides a refreshing herbal and eucalyptus aroma and moisturizes the throat for about 10 hours through steam generated from the wet filter. The mask features a high-density filter to cut airborne droplets and a 3D design for easy conversation. The mask uses soft, thin non-woven fabric for a comfortable touch and soft wide elastic to reduce ear pressure. The wet filter is white and contains parabens, fragrances, and iodine compounds.
