When I was in charge of events, I was looking for something that could hold A4 size documents, was easy to use, and didn't get in the way, so I bought this. I used it once and washed it. I bought it new about 2 years ago from an online store for around 2000 yen. It's a convenient bag with an outer pocket that can hold two plastic bottles. It has a zipper. I checked it and there are no stains at the moment, but I think it's a bag you can use without worrying about getting it dirty, haha. Please consider it.
