Tsuchiya Kaban Storage Bag Thank you for viewing. This came with the purchase of a randoseru (school backpack). I'm selling it because I never used it and just kept it stored away. It's made of canvas fabric and doesn't stand on its own, but it's well-made. It's about the size of a randoseru, so it's also good for storing clothes, etc. ・Please read the profile section to ensure a smooth and pleasant transaction for both parties.
