It's literally pumice on the handles - you rub the edge against the hard water stain to remove it. It takes a little effort to find just the right angle in the toilet and they wear out the more you use them, but they do what they promise nonetheless. I think I would be careful how hard I scrub as they could also scratch with too much pressure.
