In fact, it is a false proposition. At the beginning of the design of this mask, I bought an Asian head data from a professor of Hong Kong Polytechnic University, saying that the quarter was in line with the Asian face shape. Later, it was sold to Europe, and the Europeans did not have any problem with it. This product itself is very soft, and shoe last is not the same.
Not receiving feedback does not mean that there is no problem. After a long time on the market, customers will give feedback. I have developed medical masks before, so I know that Asian faces are flatter and less three-dimensional than Caucasians. However, there is a process: the plastic process, similar to shoes, will fit the shape of the foot better if worn for a long time, but the contradiction is that, for now, silicone is one of the non-plastic materials.
