I purchased this for my family, but they ended up buying something else, so I'm selling this. It's new and unopened. I will ship it directly in an envelope. ● This item adjusts the angle of the stroller's backrest. ● It helps to raise the upper body of a child who is slouched while riding. ● The length of the belt is adjustable, so it can be attached to various strollers. ※ Please understand that this item has been stored at home. ※ Please note that I may fold the cardboard backing for shipping.
