I've really enjoyed using this quality soap. As with all of the thankyou products this one does not disappoint. The soap is not coarse like a pumice stone (as the title suggest) but smooth and invigorating. The soap does not have a strong smell and lathers up very well for a good cleansing wash. I have not noticed any detoxifying effects of the clay, however my general sense of wellbeing is enhanced after using this in the morning (not sure if it is psychological or biological). I also love the ethos of the thankyou company and the fact that they donate profits to social projects in developing countries. Overall a great quality soap, a decent sized bar and lathers up really well - RECOMMEND. If you found this review helpful please let me know (and click below).
