I purchased multiple items, but they don't fit, so I'm putting them up for sale. They are new and unopened. *Due to shipping costs, the items may be sent without the box, but they are individually packaged, so there are no hygiene concerns. This is a great deal! These are non-woven masks that meet the Japanese Industrial Standard "JIS T 9001 (General-use masks)," which is an indicator of mask performance. The special nanofiber-processed middle layer reduces the temperature increase around the mouth during wear and alleviates discomfort caused by stuffiness. They cut pollen, virus droplets, bacterial droplets, PM2.5, etc. (*). The nanofiber-processed middle layer is used to prevent the entry of virus droplets while maintaining breathability. Soft, wide ear loops are used that are gentle on the ears even when worn for long periods. 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. Individually packaged, they are hygienic and convenient to carry. *This is the performance of the mask body only. Masks do not completely prevent infection (entry).
