Although a mask can block the spread of bacteria, it also blocks the wearers expression. For food salespeople who need to communicate with customers, being "expressionless" is sometimes not a good thing. This new type of transparent mask not only has the function of blocking bacteria of traditional masks, but also allows the wearer to show his smile, and can even meet the needs of female users to put on makeup (without damaging the makeup). It can be washed and used repeatedly and is available in two different sizes. You can also fine-tune the size to the most comfortable position when wearing it.
