<p>An ear mask which is made of a round bag-shaped, thin polyethylene resin or ethylene propylene synthetic rubber, prevents entry of water and dust into ears, and allows one wearing it to hear sounds to ensure conversations. The ear mask has a natural rubber material and cotton material attached to the peripheral edge of an ear insertion hole so as to be able to cover the ear with a natural feeling, and a pair of ear covers for right and left ears are connected to each other by one rubber cord to be set on the jaw. The ear mask can be used on both right and left ears interchangeably and worn also inside out.</p> |
