Abeno Masks Gauze Masks These are gauze masks distributed during the COVID-19 pandemic. There are 20 masks. Unopened. I am giving them away because I haven't had a chance to use them. I think they would also be useful for children's school lunch duty, etc. These have been stored at home for a long time. Please refrain from purchasing if you are concerned about this. Shipping will be via Mercari's Yu-Packet Post.
