This is a set of 13 non-woven fabric masks. The size is a general adult size. I received these at a clinic, but I'm not using them, so I'm selling them. They have been stored at home in their unopened case, so there may be some creases. The dark blue side is the inside. ⚠︎All accessories are shown in the photos. ⚠︎I have inspected the items, but there is a possibility that I may have overlooked minor scratches or stains, so please consider purchasing with this understanding. ⚠︎I will use recycled materials for packaging. I may change the shipping method between Yu-Yu and Raku-Raku. #Non-woven mask #Mask
