To avoid tears from staining your favorite clothes, It's convenient to keep these in your bag when you don't want to get your clothes dirty when you go out. These are common disposable aprons used in yakiniku restaurants, ramen shops, etc. The size is also a common size. The neck part can be tied to shorten it and is adjustable. Please refrain from purchasing if you are concerned about minor details, as these are items stored at home by an individual.
