DIY pocket button hook/zipper aid

This is a modified button hook that I made for a child whose fingers are contracted in extension. He is able to grasp items using a lateral pinch, but buttons on pants were difficult. Because of this he always wore elastic waste pants to school. He was able to button/unbutton using a standard button hook, but who wants to carry that giant thing around to school? I fabricated this out of a large paper clip and Aquaplast pellets. I made the hole slightly bigger than normal to accommodate a jean button. I curved the other side of the paper clip into a zipper hook, so that he can slip the hook into the hole of the zipper and slide his finger through the button hook to pull up. Now he can wear jeans to school just like his friends!
