This bag was a prize about 5 years ago. When I inspected it for sale, I found some stains, so please check the images. The shoulder strap is not adjustable. *If you have any questions, please comment before purchasing. Since shipping is included, I will use recycled materials and pack the bag by folding it small with the shoulder strap inside. My child has graduated, but I couldn't throw it away. I'm listing it in the hopes that someone will use it. #Dokinchan #Meronpannachan
