It is well-made and has a beautiful appearance, significantly improving dust resistance efficiency. The outer layer is 40S wood fiber eco-friendly gauze produced by the company, which is soft and comfortable to wear, with good breathability (this is unmatched by ordinary cotton gauze). It has a comprehensive role in blocking, adsorbing, and degrading N-nitro compounds and other carcinogens in fine particles. The inner and outer layers use 40S all cotton gauze, which will not cause allergic reactions to the skin during use. It also reduces the accumulation of heat, moisture, and carbon dioxide in the mask. The nose clip is installed more tightly, allowing for a close fit with the face, making breathing easier and the field of vision wider.

Simply wipe the surface dust lightly. It is generally recommended to discard the masks after cleaning them 4 times. The manufacturer has replaced the new packaging, and it is currently in the transition period between the old and new packaging. However, the quality of the masks is the same, so the goods you receive may be new packaging or old packaging. If you are concerned, please be cautious when shooting.
