Made in Japan surgical masks compliant with ASTM-F2100-19, 2 boxes of 50 masks each. Unopened. I purchased these during the COVID-19 pandemic, so they have been stored at home for a long time. Additionally, I have about 20 masks that were taken out of the box and stored in a Ziploc bag. I cannot guarantee their quality. I will include them if you wish, so please let me know if you don't mind. If you purchase without commenting, I will only ship the 2 boxes of 50 masks. - Brand: Unicharm - Model Name: Surgical Pleated Mask - Quantity: 50 masks per box - Made in Japan: Yes - Standard: Compliant with ASTM-F2100-19 Please understand that these have been stored at home by a private individual.
