This is a set of 18 one-liter milk cartons with the tops and bottoms cut off. They are all the same brand. There may be some misalignment as they were cut with scissors. They have been washed with tap water, air-dried, and stored at home. I would like to offer them to someone who understands this. #milk carton #paper carton #craft #handmade #recycle #cutting board #outdoor #preschooler #organization #divider
