It's a cylindrical bag. Used for several years during elementary school summer pool time, and then stored at home. Please refer to the photos for the approximate size. ◎ The name on the inner tag has been erased with a marker. ◎ There are wrinkles, logo scratches, marks like scratches on the belt, slight discoloration on the zipper, and coating peeling on the inside around the entire perimeter and towards the top of the surface (logo side). (Please check the photo with "裏" (back) written on it) There is no peeling on the inside of the back side or on the insides of both sides. There are no holes, and it's still in a usable condition for those who don't mind the coating peeling on the inside. When in use, towels were fine as they were, but wet swimsuits were put in a plastic bag inside, so I'm not sure if the inside is waterproof. I've washed and dried it a few times, but it's been stored for a long time, so please understand that it's a used item and only purchase if you don't mind the condition.
