An elegant mask recommended for formal occasions and everyday use. In the all-black ``mourning'' seats, the white mask around the mouth stands out. We recommend an elegant and classy lace mask. The ear straps are made of wide soft rubber that won't hurt even when worn for long periods of time. It is safe and made in Japan. Antibacterial/antiviral treated (inside) We used an original pattern that was fitted to 10 female staff members and created over 10 samples. You can also expect a comfortable fit that will make your face look smaller.
