Because it does not need the trouble of bending and nosing the nose part, it fits well, so I am using a solid type. Because Midori security superfit mask was not shipped on the day, I ordered it for trial. Cutting on the top is a unique shape longer than other companies' products, breathing difficultly on the top, cloudy glasses become less concerned much. Also, the thickness and hardness are moderate, I like the place that I do not trust. Although the size is small, it stretches well and does not matter because it has a good fit. Since it is 100 pieces, if the price is a little cheaper it is 100 points.
