Thank you for viewing. This item attaches to the side belt of a school backpack and can be used to carry long, thin items such as folding umbrellas or recorders. It can be used with school backpacks that have a side belt width of 4cm or more. Please confirm before considering a purchase. The adhesive tape on the top part is coming off in some areas. It will be folded for shipping, so please be aware of creases. Please refrain from purchasing if you are concerned, as it has been stored at home.
