My husband purchased very similar magnetic hooks about six months back, so when I saw these, I knew I already liked the concept. We use them to hang things on the refrigerator door - hot pads, oven mitts, etc. I wanted a set that I could bring to work. I have also considered adding a magnetic board on my son's wall where he can keep his things. These come with large and small sized hooks, and the large is big enough and strong enough that he could hang his backpack, jacket, and sunglasses on the wall.
