This is a 3-layer mask with 99.9% filter performance. I am selling it because I accidentally purchased the wrong color. The box has been opened for confirmation, but the inner bag is unopened. The actual color is a slightly more pastel and brighter color than the top photo. It will be shipped via Nekopos. 【Features】 It has a 3-layer structure and uses melt-blown non-woven fabric, effectively blocking viruses and pollen.
