These are great in theory, but not so great in reality. The rub-ons go on very smoothly, but there are blank spots from the way they're stored. You know how rub-ons crack along the fold if you store them folded? That's how these look -- they're not folded, but they're wrapped around a wheel, and mine show a little crack every few centimeters, as if there was a little dimple on the wheel that cracked the whole roll at one spot.
