The JOSH V Emani mask is made of breathable, double-layered material for optimal wearing comfort. The elastic fastening around the ears is adjustable. A filter can be placed in the inside of the face mask. And there is an iron wire incorporated into the top of the mask to close it properly. Note: this is a non-medical face mask and not suitable for use in medical circumstances. Guideline for using non-medical masks: wash your hands thoroughly with anti-bacterial hand gel or soap before putting on or taking off the mask. Please only touch the elastic fastening, not the face mask itself. Make sure your nose and mouth are completely covered. Wash the mask after each use at 60 degrees in the washing machine.
