Item No. 8015146 Purchased at Sogo, I didn't have a chance to use it initially. However, I used it for about six months starting around spring of last year, and then had it cleaned and water-repellent treated (costing approximately 17,000 yen). I intended to use it again, but I bought another backpack, so I'm putting this one up for sale. It's a large size and I think it's easy to use. There is a feeling of use, but there is no damage to the fabric. It has been cleaned, so I think you can use it comfortably.
