Bests & Worsts Reviews from Amazon

While the marbles where of all different shapes and sizes, more than half of the marble had wrinkles and/or marks. Some of them had cracks in them. These marbles are not made well. Marbles should be smooth and free of markings (unless, of course, they are intended markings, these markings are obviously from poor craftsmanship). A couple marbles had a flat part. One was flattened and cracked. These marbles are sub par.
