Ichizawa Hanpu fabric Kids' backpack. Please check the photos for stains. Washed. I think it's fine for small children to use, but please take a good look at the photos before purchasing. Shoulder straps are adjustable. Zippers are fine. Outer pocket is fine. The black thread-like bits on the shoulder straps were there from the beginning. The color is also very cute, so it can be used by both boys and girls. You can put stuffed animals in it. It's canvas, so it's sturdy. Thank you.
