Please purchase Kobayashi Pharmaceutical humidifying masks! ! It's a must for going out on a plane! Everyone knows how dry it is on the plane. You can use a moisturizing spray on the skin on the face after a few hours of flying, but after breathing all the time, the nose and throat will really hurt. In addition to drinking water, this moisturizing mask is definitely a savior! Comes with that kind of wet cotton pad that can be inserted into the mask with the feeling that the nose and throat are protected. . In fact, apart from the fact that if you are sick and have to work in an air-conditioned room, it is quite comfortable to wear it in an air-conditioned room, but I have to explain it to my colleagues. Hahaha, if you want to sleep on the plane, the original version has no taste. The best moisturizing mask + steam eye mask is necessary for sleeping on the plane have (just will look like a lunatic haha)
