Ten folded milk cartons. They have not been cut open. These milk cartons were collected for various uses, such as: cutting boards for children's camping trips, cooking outdoors by wrapping bread in aluminum foil inside and placing it directly over a fire, and for milk carton crafts at work. ● They will be shipped via Yu-Packet Post (reused materials may be used). ● They have been washed with dish soap, dried, and stored at home, so please refrain from purchasing if you are concerned. Since they haven't been opened and washed, it's impossible to guarantee that there are no remaining traces of milk. I live with a cat. There are no smokers in the family. Thank you.
