This is a set of 60 masks, consisting of 30 masks per box, for a total of two boxes. I purchased multiple sets, but the size doesn't fit, so I'm selling them. They are new and unopened. *Due to shipping costs, the masks may be shipped without the boxes, but they are individually wrapped, so there are no hygiene concerns. This is a great deal! These non-woven fabric masks are compliant with the Japanese Industrial Standard "JIS T 9001 (for general masks)," which is an indicator of mask performance. The special nanofiber-processed middle layer reduces the rise in temperature around the mouth during wear, alleviating discomfort caused by stuffiness. They cut pollen, virus droplets, bacterial droplets, PM2.5, etc. (*). The nanofiber-processed middle layer prevents the entry of virus droplets while maintaining breathability. They feature soft, wide ear loops that are gentle on the ears even after long periods of wear. The 3D wire in the center of the mask maintains space around the mouth, making it easier to talk and breathe. The V-cut processing on both sides reduces gaps with the cheeks, further preventing the entry of pollen, etc. They are individually packaged, making them hygienic and convenient to carry. *This is the performance of the mask body only. Masks do not completely prevent infection (entry).
