Outgrew it, so it's for someone with a small child ♡ I only used it to carry a change of clothes when moving, so there's no dirt inside. There's no dirt on the bottom of the outside either. There's a small black mark on the bottom of the small zippered section, but please refer to the photos! For those who understand that this is a used item, please. Size is approximately 25cm high x 20cm wide.
