These are 45-liter color plastic bags. The thickness varies depending on the color, with some being 0.04 mm thick and others 0.03 mm thick. I think they can be used for making costumes for plays at recitals and for crafts in events like pretend play. They are unused, but there are some creases and wrinkles. Those who understand that these are items stored at home for a long time, please consider purchasing. I will include scraps as a bonus. I think you can use them for repairs or to make small decorations when using the costumes. Please comment if you don't need them. Thank you for looking.
