this review title is: not sure this is an actual pumice and the content is: sure they look the part but i am pretty sure these are just some kind of painted concrete the i received are quite different from one another one with bigger holes only on one side and pretty smooth on the other the other was pretty much smooth with no bigger holes at all for a pumice stone they are very heavy like rocks and i am not sure why they are painted brown as it comes off in the water or on your feet i have left it on my soap holder in the shower and had a big brown streak running down the tile i would not buy this brand again.there are other information for this review, one is this reviewer did not purchase it and the other is 0 people think this review is helpful.
