This is a collaboration shoulder bag between Disney and Cath Kidston. It has been used only a few times and stored in its box. As far as I can see, there are no scratches or stains. Diameter: Approximately 17.5 cm Shoulder strap: Approximately 95-123 cm Depth: Approximately 6 cm The strap length can be adjusted in 7 stages. I think children can also use it. There are two pockets inside that seem to fit credit cards or transportation IC cards. I think it can be used by adults and children. How about using it when you go to the park?
