SUNOGE] Business Backpack Large Capacity 40L I was looking for a backpack that could store shoes and changes of clothes separately, and I ended up with this one. Besides work, it was also useful as a large-capacity shopping bag. It was especially convenient when riding a bicycle. My commute method has changed, and my single-life assignment has ended, so I no longer have the opportunity to use it. I used it to a certain extent, so there are scratches on the exterior and stains (I think it's from waterproof spray) even though I took care of it. There is dirt on the interior. Please refer to the photos. Personally, when I bought it, I thought the fabric was thinner than it looked in the photos. However, it hasn't torn, so I think it's durable. Since there is no core, I will fold it up small and pack it. Please refer to the photos for the features, etc.
