This is a chest belt for Fuwarii school backpacks. [Brand] Fuwarii [Category] Chest Belt for School Backpacks [Color] Black I purchased this for my child who will be starting elementary school in the spring of 2025. I took it out of the package thinking I might use it, and placed it next to the backpack, but it seems I won't be using it, so I'm decluttering. It has been taken out of the package, but it is new and unused. Please purchase only if you understand that it has been stored at home.
