This is a mask that is transparent around the mouth, allowing it to be seen. It is an etiquette mask designed to prevent the spread of droplets. It can be washed and reused. I never had a chance to use it after I bought it, so it was stored away. It has never been used and has not been opened. I found it while decluttering, so I'm putting it up for sale. It's perfect for situations where you want to show your expressions and mouth movements, but still need to wear a mask! I think it can be used for both work and everyday use♪
