My child complained that their shoulders hurt from their school backpack right after starting elementary school, so I bought these. I used the shoulder pads for a few days, but they got used to the backpack and stopped needing them. They were very helpful. I've lost the original clear bag for the shoulder pads, but I'll send them in a different bag. The back pad is unused. Would you like it for preparing for school?
