Thank you for viewing. After purchase, I used it 1-2 times for a short period, but since then I haven't had the opportunity to use it and it has been stored at home. As it has been used only a few times, it is in beautiful condition overall. This is a backpack with a simple and functional design, suitable for various occasions such as daily use, commuting, school, and outdoor activities.
