Thank you for viewing! This is a very cute backpack that would be perfect for use in the coming winter. My daughter used a different color and it was so cute that I bought one in a different color. I think it's the perfect size for children aged 1 to 3 years old. The shoulder straps are adjustable. It can be fastened in the front to prevent it from slipping off the shoulders. The retail price is 1790 yen. Please note that this item has been stored at home.
