I was looking for a backpack that wouldn't fold A4 files, so I bought this one, but I'm selling it because I bought another one. It's still sold in stores for nearly 10,000 yen. Lightweight Waterproof With USB port With suitcase belt Color: Beige It's designed with user-friendly pockets, even in hidden places, making it very convenient to use ✨ The functions and size are shown in the attached photos.
