Rainbow Backpack string / Backpack Accessory

Rainbow Backpack string

This helps children give a direction about leveling backpack string.
For children, it is very hard to adjust the level of bag string. Children need a reference point
to fit the both sides of bag string. If children carried the wrong positioned bag for a long time, their spines would be bent wrong.
