This is a slightly damaged Hysteric Mini backpack. I bought it a long time ago. The outside doesn't have any noticeable stains, but there are stains inside. I tried to wipe them, but they wouldn't come off. It's still usable though(^^) Please be aware of this. It's 36cm wide, about 40cm tall, and 16cm deep. It has a cute design. How about it for your child's lessons?
