This does not work on glass if for some reason you are trying to use this on glass. Since I use mine on a small kitchen table when cooking and safe. Looking to see how this affects my trunk lid in the future. I think the correct size order should be: "Little Kid 6, 10, 11, 12, 1, 2, 3, Big Kid 4, 5, 6". As always, if its too good to be true, it probably isnt true! I wear a 5, and usually dont have issues ordering shoes in my size, so I cannot get them in a smaller size. Return on next dayAnd amazon refund the amount. I give it thumbs 👍. This is my second time ordering this pair of sandal and its still my favorite. Basic ear buds but they work and sound decent.
