This is an Obakeinu knapsack. I bought it for lessons and used it for a year. It was mainly used indoors, but there are overall stains from ballpoint pens and dirt on the bottom. The noticeable ones are circled in the images, but please forgive any oversights. For those who understand that this is a used item, thank you. I will fold it up small and ship it. The shipping method may be changed. #Obakeinu #Obakeinu #Knapsack
