There are 18 masks. The masks for elementary school lunch duty come with name stickers! There is only one Doraemon sticker. The white masks and gauze masks may be for adults. There were two more children's masks that weren't in the first photo, so I added them. They are in the second photo! How about these for lunch duty, influenza, coronavirus, and cold prevention measures (*^^*) They are new, unused, and unopened, but they have been handled by someone. Please understand this before purchasing.
